 2008/11/14-26 [Computer/SW/OS/Linux, Computer/SW/OS/Solaris] UID:51989 Activity:moderate 11/14 lulz why doesn't GOOG buy JAVA i mean SUN i mean whatever the hell they are these days. \_ Even GOOG isn't THAT stupid \_ Sorry, but WHY would Google do something like that? They run 99.2% Linux servers on the backend. They don't use Solaris for development. I mean, what does Sun have to offer to anyone these days? \_ ZFS, some SMP goodness, a quality OS, some neat stuff like containers, Java, and MySQL but I'll admit it's not much which is why the price is where it is. Sun has more to offer than Apple does in terms of technology, but can't seem to connect with users the way Apple does. \_ Apple is a consumer electronics company, not a technology company. Sun's "quality" OS is being phased out virtually everywhere it's implemented. -tom \_ It is true that Solaris is dying, but it is not because it is inferior. \_ So? It's proprietary, it's slow-moving, it's expensive. If they'd community-sourced it 10 years ago it might have beat out Linux, but at this point it's dead. -tom \_ It's not proprietary nor expensive. I'm not sure what slow-moving means in this context. \_ It's not proprietary? I can release "Tom's Kewl Solaris Distribution," and mirror all the patches Sun puts out? Don't think so. Slow-moving means it's slow to support new hardware, it's slow to get vendor support for commercial/propietary applications, it has poor support from most open source packages as well. -tom \_ People do that with Redhat all the time. \_ Google is fundamentally an advertisement company. Sun is a computer hardware company. What kind of "synergy" you are thinking again? \_ I would say Sun is a software company at this point. \_ I work at the software side of Sun. and don't I wish Sun is a software company. But consider that almost 90% of the revenue is coming from hardware sales, I would consider it is still a hardware company more than anything else. \_ And yet it's not, because SPARC is all-but-dead. The only value-added Sun has is in software. They better figure that out right quick. \_ This is similar to the problem Apple faced in the mid 90s. People were saying they needed to license the OS to grow the market share for the platform, but 80%+ of company revenues were from hardware. They licensed the OS, got taken to the cleaners by clone makers, and tanked badly while failing to grow market share. Jobs came in and focused the company on hardware, found an effective niche and has been quite successful. If Sun were to transition from being a hardware company to being a software company, they'd have to be prepared to cut 50%+ of their workforce, and make a strong case for why the new software company is something that businesses should be investing in, which will be difficult since businesses are currently deciding to get rid of Sun software. Sun actually has some decent commodity Intel servers these days, but that's not going to save them. -tom
 2008/11/14-26 [Computer/SW/Languages/Java, Computer/SW/OS/Solaris] UID:51970 Activity:moderate 11/13 http://sfgate.com/cgi-bin/article.cgi?f=/n/a/2008/11/14/financial/f051352S72.DTL http://preview.tinyurl.com/6nngpm Sun Microsystems Inc. plans to cut up to 6,000 jobs, or 18 percent of its global work force, as sales of its high-end computer servers have collapsed. The drastic move announced Friday highlights Sun's desperation to cut costs and survive as an independent company. Sun's shares have fallen so steeply they've crossed an ominous threshold, driving the company's market value below its cash on hand. That means investors believe the company itself is essentially worthless. lulz is this because of open source and linuz? \_ If Sun goes down, what happens to Mysql? \_ Who cares? \_ I care a little. You may mock Mysql, but it is used by freakin' everyone these days. \_ Someone will buy Sun. heck if they're worthless, maybe I can buy Sun. I've been refraining from double lattes. \_ Sun has become DEC. It was a sad day when Compaq bought DEC. It will be a sad day when Dell or its equivalent buys Sun. -ex-Sun \_ Is this because they opensources Solaris? How do opensource companies make money again? \_ it has nothing to do with Solaris being open. \_ I am a Sun guy. I guess I am on the software-side of the house, so things are not as bad as the headline says. \_ IBM could buy Sun right now outright, lay everyone off, keep the contracts, and pay for the acquisition with the cash inside of Sun. "lulz" \_ shut up paolo \_ Bush is responsible for state of current economy! Free Tibet \_ shut up emarkp \_ You forgot to add "Iraq War" and "lolz", troll. \_ I am a Sun guy. I guess I am on the software-side of the house, so things are not as bad as the headline says. \_ As a ex-Sun employee I am not surprised. Sun has been mismanaged for 10+ years, and is full of deadwood and useless middle managers. Even this job cut won't be enough for the company to survive. Pony tail boy needs to reduce the work force down to about 10K and put an end to the java religion w/in the company is to survive in the long run. \_ As a ex-Sun employee, I think there are many reasons for Sun's problems. Linux is one reason, at least in the workstation / low-end server market. Intel is another reason. Sparc is just not all that important anymore. But the two biggest reasons I think are: (1) extremely poor management; and (2) java. Management at the upper levels was always unwilling to see reality and did not make the cuts that were needed in the early part of this decade. If Sun had cut its staff to 10K-15K in 2002-2003, they would be reasonably well positioned today. Also, Sun has way too many middle managers and upper level technical deadwood (architects, sr. staff eng., &c.). This was a problem that management was also unwilling to correct. These people are the ones that foster the java-religion w/in the company. It doesn't matter how lousy a java project is, it will always be selected for funding over a non-java project. In fact, I saw profitable non-java projects cancelled in favor of incomplete and unreleasable java projects. The only reason for these cancellations was that the profitable projects weren't using java. \_ Religion? You mean cult. -I hate Java \_ http://finance.yahoo.com/q/bs?s=JAVA Cash on hand is 2B, market cap is 3B, so your first premise is incorrect. Also, what you should really be looking at is real tangable assets minus liabilities and that is even less, more like $1B. But JAVA really is cheap. \_ I disagree. Take a look at: http://finance.yahoo.com/q/is?s=JAVA http://finance.yahoo.com/q/is?s=JAVA&annual Maybe I am not reading this right, but it looks like Sun has lost about$1.3 billion to date this year, and lost $864 million in 2006. This trend is not new and reflects the unwillingness of Sun management to face the reality that fewer and fewer customers need sparc, java, zfs, &c. and that too many people are employed in developing things that no one wants to buy. - ex-Sun that no one wants to buy. -ex-Sun \_ Look at the cash flow chart: http://finance.yahoo.com/q/cf?s=JAVA&annual They had positive cash flow in both 2006 and 2007, and while 2008 cash flow is negative (through June), cash flow from operations was positive; the negative hit is on sale purchase of stock, which probably means they spent some cash to do a share buyback. (Which was probably a mistake, looking at the overall situation). In general, they're not bleeding money; they're just becoming less and less relevant. -tom \_ They are burning through$250M per quarter, which means they have a year left if things don't turn around quickly. \_ Actually, it looks they just need to stop buying their own stock. \_ Ponytail can do no wrong. Really does anyone take seriously a man in a ponytail? \_ My Little Pony

DoS? \- back in the solaris say 2.5-2.6 era, it had both some bugs (some malformed nis maps made it go crazy) and architectural flaws in the IPC/door+threading mechanism. if you are running OS-recent, dunno, but you can trace it. \_ Yeah, I think it's just buggy.

 2008/3/30-4/6 [Computer/SW/OS/Solaris] UID:49614 Activity:nil 3/30 Question: I just deleted 60 GB of files from an 80 GB disk. The disk activity lights were blinking like crazy and I could hear the drive crunch while the data was deleted. This is under Solaris. Anyway, I think UNIX uses unlink() when files are deleted. Shouldn't it just update the free list on the superblock and call it a day? What is all the crunching about? \_ Well, I guess it depends on how you delete it. I assume you did 'rm -rf *'? In that case it would go through all the directories delete each file by name one at a time. You could get the behavior you were hoping for by formatting or rewriting the partition table.

 2007/11/27-30 [Computer/SW/Languages/C_Cplusplus, Computer/SW/OS/Solaris] UID:48701 Activity:high 11/27 I'm using select to do a nonblocking check to see if a single socket has anything to read off it. Problem is, I can have up to 12228 file descriptors, and Linux fd_set only supports up to 4096. Any idea what I can do about this? (Or a better solution?) -jrleek \- 1. who are you 2. i am busy this week and you didnt mention language [i am not fmailar with stuff like java nio] but you might look at this ucb/cs paper ... matt welsh et al "a design framework for highly scalable systems" as well as some of the discussion around libevent. see the links and graph at http://monkey.org/~provos/libevent \_ Ah, the program is all in 'C', but it needs to run on multiple Unix variants. -jrleek \_ Have you profiled it? Can you port to python or another scripting language with reasonable performance (alas, not ruby at this time)? -dans ruby at this time)? At http://Slide.com, a hot startup in downtown San Francisco (we're hiring!), we open AND close millions of socket connections every day. -dans \_ How could I profile it? This isn't a webserver, it's a server that accepts, and acts on, messages based on a protocol I wrote. (Over TCP). In this case, I need to know about the performance of a tiny part of the code. I'm not sure how to get that information. gprof, for example, doesn't seem to allow me to choose just a small section to profile, and lacks the necessary resoluton anyway. -jrleek \_ What you want is a profiling tool that doesn't work via random sampling but that lets you add profiling hooks into your code. I've written some homegrown things like this in the past to profile very tight loops in massive projects, but I'm sure there are plenty of better tools out there if you poke around. \_ Hint: leek >> dans. Why are you listening to his babbling? \_ Well, I have a lot to learn about network programming, so I'll take what I can get. Thanks for the compliment though. -jrleek \_ Alas, I don't have any better suggestion that gprof, though there must be better tools out there. Another alternative would be to compile the source, look at the ASM output and try to hand optimize. Consider that a WAY last resort, and not worth pursuing unless you're already a fan of ASM. Two problems though: there. Another alternative would be to compile the source, look at the ASM output and try to hand optimize. Consider that a WAY last resort, and not worth pursuing unless you're already a fan of ASM. Two problems though: a) it doesn't really scale if you need to target multiple platforms and b) it's actually tough to beat a *good* modern optimizing compiler even if you really know what you're doing. -dans \_ UPDATE: I just asked one of the guru's and he responded, 'books? what are those' see: http://www.kegel.com/c10k.html It's more of a jumping off point, but it will at least give you tools to work with and references potential implementations. -dans \_ Hint: In the last three years have you... a) worked on a project with me? b) read or hacked any code I've written? c) used a service based on my code or systems I administered? Unless you can answer yes to at least two, you have NO FUCKING IDEA WHAT YOU'RE TALKING ABOUT. Why two? Because I built the systems half (as opposed to the network/routing half) of the anycast DNS rig that runs the roots for over fifty ccTLD's including, amusingly enough, .cx. Thus, the answer to c) is almost always yes. -dans \_ Use poll() instead of select, or do multiple selects with several different fd_sets . -ERic \_ Can you increase the max size of fd_set in /proc? I'm guessing not, but couldn't hurt to look. Also, using select on that many file descriptors will probably result in sucky performance. -dans \_ Do you know where I can read up on getting really good performance out of the POSIX tcp codes? \_ I wish I did. Most of what I know is a collection of voodoo and lore. It's not super complicated, basically you want to use non-blocking sockets and poll. Also, avoid threads unless you know what you're doing. Writing correct threaded code is hard, writing high-performance threaded code is even harder. On Linux, processes are basically threads, but with processes you don't have to handle any locking crap. -dans \_ epoll (linux) or kqueue (bsd) \_ Unfortunately, it needs to run on AIX (IBM's Unix) as well. \- arent you that fellow at livermore? if this is going to run on ibm big iron, maybe if you have a "user services" group they will know this. cray and ibm have some people group they will know this. cray and ibm have had some people stationed here as part of nersc. i am familar with assos, fleebsd, and solaris [/dev/poll] but not aix. btw some of the select vs poll people seem to be unaware of many places where the interface is different, but under the hood they are the same thing. --psb fleebsd, and solaris [/dev/poll] but not aix. --psb \- i have never heard of/used this [i no longer work on aix] but check this out: http://tinyurl.com/26z9jf [pollset] often i would think if there was something that was obscure it probably wouldnt be that good, but in this case 1. ibm has a history of sitting on good things that fail due to obscurity 2. i'm not in the loop [no pun intended] any more on ibm stuff --fmr ibm person \_ We do have such a group, but they don't know much about TCP. It's kind of an odd thing to be doing. I wrote this TCP implementation as a proof-of-concept, but we've never gotten to money to do something better, so I just keep trying to improve it incrementally. -jrleek
 2007/7/9-12 [Computer/HW/CPU, Computer/SW/OS/Solaris] UID:47240 Activity:high 7/9 Are 64-bit Linux servers popular compared to 32-bit ones? My company has a server product that supports 32-bit, and we're trying to see if it's worth supporting 64-bit as well. Thanks. \_ in my company, everything linux is 64bit except the handful of redhat satellite servers, because redhat's sat server product doesn't support running on 64bit systems (yet). DOH! \_ Compared to 32bit? No. Whether it is worth it to support or not depends on a lot of things, but mostly the desires of your customers and the cost of doing supporting it. customers and the cost of supporting it. \_ It has more bits so it must be better! Seriously though, now that 64 bit is here I think you'll find most places doing 64 bit. The best people to ask are your current customers. Unless you're making a pre-packaged toaster product, then it doesn't matter. \_ No, you will not find most places doing 64bit. It's still early. \_ Maybe at your place. See the person below for an exmaple. \_ I went to USENIX recently and 64bit is still far from the norm. \_ No 64bit at all in most of the places of USENIX attendees? You know this how? \_ Did I say: "No 64bit at all?" No, I did not. However, the topic came up in a session and only a few people said they used it in production. \_ Representing how many servers and which companies? Was this the "64 bit linux" session? \_ How many are represented by you and two other MOTD trolls? \_ Oh, ah, personal attack! Way to go! You are right, 64 bit is DOA. How many? Like the other poster we have been building only 64 bit boxes in the last few months and have the remaining non-64 bit scheduled for termination over the coming months. Maybe your place of business is just too small or doesn't do real work? \_ I never said it was DOA. It will gradually become the standard. However, it is currently not the standard. Even you admit that you only started to switch over a few months ago. \_ You trolled. I sarcastically trolled back with the DOA overstatement. I admit nothing. I told you we've been at it for a few months which started last year and continues forward as we have time for it and new machines come online. I expect most places will be doing similar gradual rollouts. The idea that a few usenix attendees at a single session is representative of industry is no more likely than your 'motd trolls' as you call us are representative of industry. Less so since we're actually here to discuss it with you, not a vague 'please raise your hand' at a session. Again, this isn't rocket science stuff. 64 bit linux is a big thing for some people, nice for most and harmless to most of the rest. Only a few with custom apps or low loads won't get anything from it. Unless you *know* you don't want 64 bit, you want 64 bit. And just because it isn't being rolled out in bulk doesn't mean it isn't the thing to do. Quite the opposite, that means it is the thing that is being done right now as we speak and doing a gradual rollout is the smart way to go in most shops. \_ I was disputing the "most places are doing 64 bit" statement above. Most places are not doing 64 bit for production. You allude to that above with your gradual rollout statement. 32 bit is still far more pervasive than 64 bit at this time. \_ If they've got 64 bit in production right now as part of a long term roll out then they are doing 64 bit in production. Just because they didn't flip 1000+ machines in a day doesn't mean they're not doing 64 bit. They're being smart. Any place with that many machines is going to do almost any change like this in a gradual rollout. Why is 'production' so hard to grasp? What is your tech focus? Programming? Sysadmin? Manage- ment? Something else? \_ We are 3/4 the way to converting to 64-bit everywhere. We should be done by end of year. -Ops guy at company with 1000+ servers \_ Why are you converting? \_ Because the 32 bit limits suck for real computing. !gp \_ Then you should've been running Solaris all along. Why was 32 bit okay 12 months ago and suddenly not good enough now? I can think of some reasons why you'd have to upgrade to a 64 bit OS on a 32 bit processor, but they are not common ones - mostly a need to address massive files or memory - hardly a reason to upgrade every server at a company for the hell of it. \_ Solaris = not free. 32 bit 12 months ago = sucked then with lots of work arounds. 64 bit now = it just works. Convert everything because it is easier to maintain fewer images/builds. This isn't rocket science. Why do you think a place with 1000+ servers doesn't have 'a need to address massive files or memory'? 2 gigs is hardly 'massive'. I've got games that require more ram than that.. \_ Solaris is free. You can have more than 2GB of RAM or a 2GB file with a 32 bit OS. You don't need a 64 bit OS for that. \_ Solaris is not free when you have to buy real hardware to run it and you knew that. If you're talking the x86 version, get off the motd. \_ I didn't know Linux came with free hardware. \_ The OS is now free, x86 or not. The hardware is not free, but neither is Intel hardware. If you are worried about x86, what does Linux 64 bit buy you? \_ The OS has been 'free' for years but useless without the hardware. And Sun hardware is way more expensive than x86. If I want a production quality system running Solaris it will cost more than a linux 64 bit system. That is why Sun is dead and linux continues to grow. \_ You can run Solaris on x86 and the hardware costs will be the same. If \_ Solaris x86? Whatever. We are talking about production 24/7 systems that real people support, not your Quake4 server. \_ The code is the same. I repeat, this is not x86 circa 1992. \_ Quake4 server. 2007. you want the Sun hardware then the premium is not as bad as it used to be. An Ultra45 costs maybe $6K versus almost$5K for a high-end Dell. \_ Great, I just spent an extra $1k for what exactly? And how much does Sun support cost on that box? \_ For a true 64 bit CPU. A Linux 64 bit system running on a 32 bit chip is not true 64. If you \_ Who said these are 32 bit chips? Where'd you get that idea from? \_ Which 64 bit chip are you running on then? \_ So you're going to claim that the current gen Intel/AMD x86 chips aren't 64 bit? This is going to turn into a philosophy debate on instructions sets now, huh? \_ Yes, I would claim that the current gen chips are not true 64 bit chips. They are 32 bit chips with 64 bit extensions. \_ distinction being? as in, why should I care? want 64 bit Linux you need to run on something like Itanium and that's not cheap either. However, did you \_ Who said Itanium? Did we flash back to 1998? This is 2007. Both AMD and Intel are selling true 64 bit chips. Hello? \_ Yes, and Intel's is called the Itanium - IA64. \_ See above. realize that Solaris x86 is not the same crappy product it was 15 years ago? \_ Sun is hardly dead. You can get a 16 \_ Solaris x86 is the same crappy product it always was. It is a niche product which makes no sense in 99% of the real world. \_ Solaris has a lot of features that Linux does not have. \_ Solaris does but who is running Solaris x86 in a real production environment? I'd be surprised to hear of any place with more than a handful in 24x7 and have a heart attack plus a stroke if anyone is doing thousands of solaris x86 anywhere. \_ Why does Solaris x86 bother you so much? It's the same OS as Solaris SPARC. A lot of Canadian companies are using it, FWIW. I would consider using it in order to use some Solaris features like ZFS (until Linux gets it), the scheduler, and containers. \_ Sun is hardly dead. You can get a 8 core T1000 for$5k these days and its operating costs will be less than 1/4th what 4 dual core Intel boxes would be. \_ What about 1 dual chip quad box? :) The T1000 is not so useful for floating point, but it was good to mention it. I had almost forgotten, since I mostly care about floating point. Also, IBM's new Power6 chip will run Linux, too. To claim you need 64 bit computing and then run it on a 32 bit CPU is laughable. I will eventually run 64 bit Linux on i386, too, but to think that most people (or even a sizeable fraction) are doing so now is deluded. We are just now starting to port over most of our major s/w, although we started a year ago, and it will probably be another two or three years before we can drop 32 bit entirely because of all the testing. A rule of thumb is that it takes about 5 years to throw old hardware/software out the door, so I expect there will be a lot of 32 bit Linux for some time yet. Realize that there are companies still running VMS and DOS. \_ Our older 32-bit servers needed to be upgraded, so we decided to roll out new 64-bit servers with 16GB of RAM. We have lots of apps that need to address more than 2GB of RAM, or we can make better use of the new faster boxes by addressing more RAM in the java container. It is easier in the long run to only have to support one platform, rather than two, also.

I have considerable experience running many virtual interfaces on Linux and Solaris, email me if you want info on how to do it. -dans \_ it is hard to create virtual interfaces? \_ No, it's a couple line changes in a config file (which one varies by Linux distro or Solaris) or a manual ifconfig invocation.

I can't even figure out how to lock a yppasswd on solaris. Help. \_ Hint: Your issue is not with NIS \_ Uhh, what is it with? \_ Solaris' passwd mechanism doesn't provide a locking mechanism (unless it's a recent addition i don't know about) \_ from shadow(4): The lock string is defined as *LK* in the first four characters of the password field. --Jon \_ further note, you can use NP as the passwd string which will allow uid to run cron jobs/etc --Jon \_ Which you should not be using anyway... \_ Well, I don't fault people using NIS in a secured corporate environment. \_ Hard on the outside, soft and chewy in the center. \_ I've worked on a lot of networks and they have all been like this (well, hardER on the outside anyway, some were pretty soft all around). \_ Probably, but with NIS you may as well not even bother with security. \_ NIS really isn't that bad in terms of security if you have strong passwords enforced. NFS, that's another thing. -tom \- you need more than strong passwds. you need tight securenets, you need to not let people log into servers, you probably need the servers hardcoded to the clients etc. in many environments sniffed credientials are now a bigger problems than cracked passwds. once somebody gets unauthorized access to an unpriv nis account, it is highly likely they will be able to find some local exploit. and without the other issues raised above you are potentially vuln if a machine not even in your domain but just within your bcast domain is rooted. that being said, i think nis has its place but that is beyond the scope here. \_ I didn't build the system, I was just hired to make a few changes, not rebuild it. -top \_ One good and fairly secure alternative to NIS, if you don't want to go with with LDAP, is to setup cfengine to rebuild /etc/{passwd,shadow} files on all machines. The downside of doing this is that if someone roots a client box they can still see your local /etc/shadow file.

This seems (based on my bad memory) to be contrary to my experience. Any opionions on duping an inuse disk (to a non-inuse one). this is on solaris 8. \_ live update, ufsdump, rsync, dd... you want your filesystem as quiesced as possible though for all of the above \_ what the above and others say about quiet drives and RO and then: since you don't tell us what problem you're trying to solve, my very generic advice is this: dd the drive so you get boot blocks and other fun stuff you might want, then do an rsync after that just for kicks in the hopes of catching a few of the files that might have been in use while doing dd. no, this followup rsync will not make a perfect mirror on an active disk but if you wanted to do a real backup, you'd use real software for it or at least take the source drive offline. you're well into kludge territory already, anyway. \_ You can dd from a disk that is in use. You will obviously not get an exact duplicate and, as above, I would not try this on a very busy filesystem. However, it works fine under Solaris 9/10 and Red Hat Linux. I've done this to make 'backup' disks (successfully) many times. \_ If you need to keep the filesystem mounted RW, I'd suggest using rsync rather than dd. If the filesystem is mounted RO it seems like dd would be fine. \_ Rsync is slower and won't grab the boot blocks (if you want them). \_ rsync is NOT slower than DD unless the filesystems are basically full. -top \_ Yes, it is. Best case scenario (using the right rsync options) they are about equal. "dd" can use the raw device and bypass the filesystem entirely. Amended: You are right that if the filesystem/disk is not very full then "dd" will be slower merely because it is copying "empty" space but not because "dd" is intrinsically slower. \_ What problem are you trying to solve? What are your priorities? \_ so it's not "intrinsically slower", it just takes longer to run? Get a clue. -tom \_ I think you need the clue, tom. "dd" is faster. If you want to prune the list of files you want to "dd" first it will kick the butt of "rsync". You know that, too, but you just like to argue. When copying the exact same volume of data, "dd" is faster. \_ While driving a car is faster than walking, walking from Telegraph and Bancroft to Telegraph and Durant is much faster than driving. "dd is faster" is meaningless unless the problem is well-defined. -tom \_ Even your example is false. \_ Alright, we're convinced: you're an idiot. You don't have to try this hard just for us. \_ You may as well say that a plane is slower than walking, too. The statement about a 'well-defined' problem is your own parameter but doesn't change the fact that planes are faster than walking. \_ To put this in a way that even an idiotic computer geek might understand, if you have two different sort algorithms, one that's usually faster in practice but O(N^2), and one that's usually slower in practice but O(N log N), it makes no sense to say that one is intrinsically faster than the other. It depends on the problem you have to solve. -tom \_ HAMMER GOOD! If you took a second to think, you'd realize you're clueless. Or maybe not. It's dim. \_ Do you know what the word 'intrinsic' means? \_ Yes. You seem to have trouble with the word 'slower', though. \_ "dd" is intrinsically faster. \_ Not for the problem posed (ergo "HAMMER GOOD"). If you want to keep spouting your technically correct and completely irrelevent point, by all means... You will still be wrong. \_ You have come to know that which is tom. \_ hey moron: he's replying to !tom. \_ We don't even *know* what the problem posed is yet. However, we do know the guy wants to use 'dd' to solve it. Rsync may not even be a viable solution in this particular case. \_ What problem are you trying to solve? What are your priorities? \_ try using solaris' Volume Manager (also known as disksuite). create a one way mirror containing the current live FS as the initial submirror, then attach the second empty FS as another submirror. wait for the second submirror to sync up, then at your leisure, detach the second submirror. look at metadb, metainit, metattach, metadetach, metaclear, and other "meta"commands. --Jon look at metadb, metainit, metattach, metaoffline/online, metadetach, metaclear, and other "meta"commands. --Jon \- i have a solaris 10 sunblade 1500 which some colleages wanted to clone to save time. i rebooted my machine and used /usr/bin/dd if=/dev/dsk/c0t0d0s2 of=/dev/dsk/c0t1d0s2 bs=1000k and thne fscked. all the machines work fine ( 5 clones). it sounds like you know what the issues are so just take this an a data point. 73gig disks ... i think it tok 40min or so. oh i am sure i booted it su and killed off most of the processes before running dd. \_ The thing with the Solaris LVM method is that you don't really need to have the filesystem quiescent.

 2005/5/5-6 [Computer/SW/OS/Solaris, Computer/HW/Laptop, Computer/HW/CPU] UID:37529 Activity:kinda low 5/5 I am not familar with Solaris, so, I may be biased... My impression, from a desktop/laptop user point of view, is that Linux has better userability than Solaris10, eventhough Solaris 10 also come with a gnome desktop environment. However, I find myself in a rare position of not knowing how to articulate this point to some of the Solaris fanatics. Their argumenet is that since S10 is also equipped with GNOME, userability is the same as Linux. 1. is this arguement flawed? 2. if you think Linux indeed has better usability, any concret example of userability is more than gnome desktop TIA \_ From a user point of view, the biggest advantage of Linux is all the software it ships with. All of that *can* be added to Solaris, but it isn't there out of the box. Another advantage of Linux is that for most tasks the actual hardware is faster, assuming you are running Intel/AMD. Sun has the advantage for problems that fit within the larger CPU cache, but are larger then the (smaller) Intel cache. \_ No Linux desktop user has any basis for say his desktop is superior in usability to the S10 desktop. This is like the dateless ugly girl at the dance picking on the other ugly girl for not having a date. \_ Thanks for erasing my post and adding bullshit at the same time. \_ it's ok, I read it already. -- OP \_ that is why I post this on motd. If i think i am in a position of being objective, i probably can make assessment on my own. having said that, from little things such as ls, man command, to the way driver installed on S10, I still think Linux is friendlier. \_ BWWAAAAHAHAHAHA! Man, it's 'friendlier' until you have to do low down systems level programming. Then it's 'friendly' in the same way your 320lb cellmate 'Butch' is friendly. \_ ^320lb cellmate^neurotic 320lb cellmate \_ Is that what the server world has really come down to? One version of 'ls' is "friendlier" (meaning: the way you learned it on the one system) therefore that system is superior? I'm curious how many non-Linux systems you've used and for how many years each. \_ Your point is correct, but I've just watched (again) a bunch of presentations tearing gaping new assholes in Windows security. Maybe he should have mentioned this. Usability is actually pretty decent. -John \_ What about drivers? Unless you buy hardware from Sun, you're going to have some serious problems with hardware support. In addition, the number of binary-only desktop applications seems to be dwindling (for example our users would like to be able to use the latest Matlab and Acrobat reader but those aren't available on Solaris/x86). In addition, even though Sun includes Gnome, I doubt Solaris x86 comes with as many popular open source applications as there are in a typical Linux dist (but then I could be wrong, I haven't used Sol10 myself yet although Solaris 9 loses hands down in this area even though it also comes with Gnome). \_ Easy fix for that: just buy Sun hardware. \_ I don't understand the desire on the part of some people to attempt to compare the quality/friendliness/whatever of the desktop environments of what are really server systems. If you want a nice GUI, buy a Mac. If you want to play games, work in an office, and have the largest variety of desktop apps, buy Windows. If you want a server system and you're the one making the buying deicision, the question is not "Is this Gnome better than that Gnome?" The question you're answering and the 'debate' you've involved in is meaningless. \_ Someone has to develop the apps for the server system and that lucky person often gets to use it as a desktop. It is true, though, that using a PC/Mac as one's desktop and remotely connecting to the server to code makes sense depending on the app being developed. \_ Yep, I've got the kind of luck where I have to use CDE at work. As far as desktops go, Linux is easier to use on x86 because there are just a lot more people using it and improving it. Also, I'd have to say GNU utilities are generally superior to default solaris ones.
 2005/4/29-5/1 [Computer/SW/Security, Computer/SW/OS/Solaris] UID:37425 Activity:moderate 4/29 Why did Sun decide to implement SMF in Solaris 10? Was it just to piss off customers or is there some technical advantage? \_ Are you talking about the new way to start/stop programs, &c.? If so, I must agree that the only purpose was to piss off customers and prove that Sun can do something stupid and different than Linux (chkconfig may not be great, but it mostly works and everyone knows how to write init scripts) BTW, SMF pissed off a lot of ppl inside sun who have to ship products on other *nix than Solaris. \_ I guess Sun should be on http://fuckedcompany.com if it isn't already. \_ Can someone give me a list of reasons why SMF is bad? \_ Complicated new way to do something that has already been done. Like I said, if there's some technical advantage then I'd like to know what it is. Maybe there is one. If not, it is just change for change's sake. \_ 1. SMF uses non-standard commands - you can't simply start/stop a process by calling its init script, you have to know what its SMF "name" is. Even if you don't have to deal w/ other *nix, SMF makes switching btwn S9 and S10 a pain. 2. SMF enable/disable semantics are bizarre - you can't just say enable/disable X like in chkconfig and assume that the daemon is enabled 3. SMF fails to provide adequate feedback re failures of configuration. Often, you can't tell if a fault needs to be cleared in order for it be enabled. service can be enabled. 4. SMF's files are non-standard and their contents are not explained well - the purpose of SMF is to make fault recover/mgmt easier, however if most of your admins don't/can't figure out how to fix config problems, faults will take longer to remedy. Developers and Admins should not have to read some guys blog on http://blogs.sun.com in order to get details on how the system works. \_ http://docs.sun.com/app/docs/doc/817-1985/6mhm8o5n0?q=smf&a=view \_ Yes there are docs, but the docs don't really have anything useful in the. Ex. tell me where in that page it specifies how to use svcadm to disable a process from being started or how to tell if the reason a particular process is not starting automatically is b/c SMF thinks that the process is in 'fault' state and must be cleared. 5. The fault mgmt functionality provided by SMF could easily have been provided through additions to existing functionality (specific args to init scripts, allowing apps to dump monitoring scripts into a given directory, &c.) \_ Sounds like one of those numerous cases where Sun was trying to solve the problem which has been already solved by others and comes up with some terribly complicated and non-standard way of doing things. *sigh*

Don't they realize that if you're going to have a large install base that you can't arbitrarily do crap like that anymore? \_ I agree that they are lame and have always have been, but Fedora isn't a production distro.

Many times it is hard to justify the added cost of installing EL and a customer choses to deploy FC. You don't really have a choice but to support FC as a application developer. It isn't really practical to tell a customer to install Debian 3.0R3 or something. \_ yeah but the bug free version is GPL also. you can try to use CentOS or one of the other RHEL redistributions. unfortunately they still suck as a consumer OS. actually scientificlinux.org looks interesting. \_ They break drivers all the time anyway as far as I could tell. You're supposed to stick with some old kernel for a long time for actual consumer use. But why would you need drivers for Linux? It's not like you can play games or really do anything anyway. \_ Well, unfortunately since Sun did such a bad job maintaining market share us EDA folks are being forced into Linux. Now we have to do do crap like recompile the kernel just so the stupid display driver works. \_ Yeah I use that stuff at work. As long as other people are responsible for making it all work I don't really care. \_ I compare the adoption of linux by corporate america to the ubiquity of windows. Some mid-level managers and idiot salespeople who thought it gave them cache foisted it upon the world where it went batshit crazy and drove us all insane. \_ I actually prefer Linux to, say, Solaris or HP-UX. It has its limitations, but overall it is cheaper, faster, and easier to maintain in many ways. \_ ditto. -- SUN guy \_ No offense, but Solaris is a far better operating system. Just because for a long time Solaris didnt ship with perl and you have to build you own tcpdump doesnt make it otherwise. If you get involved in the innards of operating systems, this is pretty clear. There are some SysV things that arent ideal, but if you are trying to debug low-level things, it is pretty clear. \_ Not to mention that drivers actually work in Solaris... \_ Linux has far more working drivers than Solaris. Solaris just works on the very limited hardware Sun provides. -tom \_ I work for SUN and I've been fighting on driver issue everyday. And I can tell you flat out that you may think driver works on Solaris, but Linux is the only way to go. People would write Linux drivers, but SUN relys on 150 people in Beijing to crank out those things one by one. As hard as those Chinese monkey works, they can never match the speed which hardware comes up. \_ You must live in some other universe. I work for Sun and we have the hardest time getting drivers to work for even simple stuff like gigE nics (ex E1000 driver on S10 was a nightmare for a long time). And you can forget about AGP in most cases. Some big shots felt AGP was the shits so no support in Solaris. There were several cluster deals we couldn't bid on b/c there was no AGP support in Solaris. \_ hey, would you mind if I contact you? -another SUN guy (id 152093) \_ I think you may be missing the forest for the trees here. How many people spend their time debugging low-level things?'' How many people just want the system to come with a modern version of perl? Once you reach a critical threshold level of stability (which Linux hit some time in 1999 or so) comparing OS internals dick size becomes pointless. \- if you want to say linux is more useful because i can surf my p0rn and play my mpegs "better" that's fine. useful to me != better os design. it's not a matter of how many people do this. it's more like looking to a kernel crash dump tells you a lot about what is under the hood. \_ In the REAL world, most people write applications that run on the OS. I can almost understand that Sun doesn't want to ship MySQL or PostgreSQL w/ Solaris, but WHY IN PARTHA'S NAME did they wait till S9U3 to ship wget in /usr/sfw and S10 to add gcc? I shouldn't have to go to some website to download badly packaged freeware. Every single Linux distro comes with this stuff pre-installed. Oh yeah, instead of chkconfig and isc dhcpd I get svcadm and sun dhcpd which are complete CRAP. Linux has its own problems, but one HUGE advantage of Linux is that you can tell your customers to get RHEL 3 ES or SuSE Pro, install it in server config and then install your software on top of it. The same RPMS every time, in the same location, it makes it easy to test, debug and support. Unlike Solaris where you have to ship all your 3d party pkgs you don't have to worry about keeping up to date with DBI.pm fixes, PostgreSQL security patches, wget vulnerabilites &c. The OS vendor takes care of that so you can concentrate on your app. \_ and for your information, MS Windows hit that threshold by year 2000 with Windows 2000. Despite you may not think that way. \_ \_ I don't. Solaris + Native Sun HW is definitely a lot easier to setup and better integrated than Linux. Solaris x86 on the other hand makes zero sense. Sun HW also used \_ let me tell you something. The biggest mistake SUN ever made was terminate its Solaris x86 program back in 2000. Since then, Linux took off. -SUN guy who is trying to sell Solaris10 everyday. to be quality, of course since the U-Sparc 5/10 days this is no longer true. HP-UX is basically dead, has been since the late 90s. I just think it's really lame that in the year 2004 I have to recompile the stupid kernel to get something like UDMA to work. In some ways, Linux sucks because it's just a rehash of 30 year old tecnology on cheap commodity hardware. I mean, shouldn't there be something better than what's essentially just glorified UNIX? In all the years with Linux I haven't really seen anything that really was groundbreaking in terms of kernel dev. I mean, wtf was Torvaldis smoking when he decided he was too lazy to implement a modular structure to the kernel, and why hasn't this been corrected in the 15 odd years that Linux has been around? \_ What Torvalds was smoking when he decided he was too lazy to implement a modular structure in the kernel: http://csua.org/u/ale You may bitch, but history shows him to be correct. \_ "correct"... Linux has become more modular over time, and other OSes haven't sacrificed their modular design at the altar of Linus. What exactly was he "correct" about? That linux beat minix? Big whoop. \_ Hah, exactly my point. It's like saying that the Chinese had stopped charging families for the bullet they execute prisoners with. Going from the Americans had stopped genociding people for human rights, freedom and democracy. Going from crap to not so crappy isn't exactly innovation. \_ the bigger picture is not about technical superiority. and i was hoping you guys notice that when Windows captured 98% of the OS market while argueably it is the worse major OS on the market right now. \_ No, the point was that Windows 98 was backwards compatible with Windows 95 which was backwards compatible with Windows 3.11, etc. Now Linux version 2.6.6 isn't even fucking compatible with Linnux version 2.6.5. That's progress? \_ Man, this whole thread could be summarised as: OP is upset that Linux community doesn't care about 3rd party drivers, and many CSUAers continue to deride Linux for not being enough like X \in { BSD, Solaris, DomainOS, ... }.
 2004/12/1 [Computer/HW/CPU, Computer/SW/OS/Solaris] UID:35146 Activity:high 12/1 open source sadness, SUN being destroyed by linux.. \_ More like Sun stupidity by refusing to either A) Make Solaris x86 free until it was too late. B) Give up on the stupid "java thin client" crap C) Open Source Solaris and let people actually write drivers for 3rd party peripherals. D) Standardize on a PC architecture instead of dragging on forever with a dying USPARC platform. \_ Re: C), Why does it need to be open source for people to write drivers for 3rd party peripherals? XP is not open source, but people can write drivers. \_ Obviously you don't understand software/hardware economics. Unless your OS has a large entrenched user base (such as Windows) nobody is going to spend money on writing drivers for it. It's economically unsound, especially if you have to buy the tools. Solaris didn't even come with a free cc compiler (SunOS did). As for writing drivers for XP, it costs in the neighborhood of $10,000 to develop a driver for it (I know, I've been involved in one). Solaris needs to be open sourced so that OSS people can port Linux drivers to it (which has been done before) or write drivers from the ground up, especially on an X86 platform. Apple's OS X would have faced the same problem if it had jumped onto the X86 platform. \_ I am glad. I was a big, big Sun customer who kept telling my reps that we were going to move to Linux mostly because of cost since we actually prefer Solaris. Most of us don't care about the OS price (cheap) or whether it is open source. It's the Intel hardware that was much cheaper and drove the decision. My reps had the attitude that we were small potatoes since we didn't buy lots of E10Ks and that it was fine for client-side to be Linux as long as they could sell their expensive servers. Now they are paying the price for not listening to their customers... \_ Not just that--I've encountered some pretty serious incompetence here.

We can do this because we run all Sun hardware and software. Tell me a place that runs linux and does this. -Sun fan \_ Any place that runs Linux on an AS400, dorkus. It's called IBM, they are going Linux, it's well supported, and runs like a charm. \_ You know, administering 100 (likely similarly configured) machines is not really _that_ hard for any competent sysadmin as long as they run some form of *nix. \_ Sun is out to destroy itself. Sun Service's new trick is to come in, declare all the SA's overpaid, and replace them with Sun Service H1-B's making $20/hr. -ax \_ It is more like.. if they get destroyed, it would be because of their own stupidity. They should have seen the Linux/x86 threat coming a long time ago. Granted, they're ARE embrassing Linux and x86 now and have plans to open source Solaris. So, it's possible they're not a toast yet. Though, their sales people STILL don't understand that the time when they could have made thousands and thousands of profit per machine sold are over. The other day I was looking at their education promotions page, and the best deal for "low-end" server is a dual USIIIi rack box that costs$7000. Say what?

The descriptors are in an array. In order to find an empty slot in the descriptor array the kernel has to traverse the list. During the early days of SunOS this was found to be rather expensive. So instead a bit field was devised in order to determine used and open descriptor slots. And guess what they used for the bit field, a byte. Since process info has to be stored in kernel memory, this was seen as saving space, so each process had an associated bit field for the descriptor array. Hence the 256 limit. \_ welcome to a new century. the default hard limit is now 1024. see below, limit is 256 only for standard library functions, and this is removed on 64 bit solaris 7. go figure. and i did say solaris, not old SunOS. \_ Solaris max is 256 for 32-bit apps.

I've never had any problems. what do you mean linux "flailing on large data"? \_ I throw around 2 terabytes of data with linux every other day and I haven't noticed any data loss yet but I have not conducted an exhaustive statistical study. - danh \- do you guys actually check the data or do you cross your fingers? obviously if you dont look, you wont find. also it may not manifest itself withing a certain range of behavior/configurations. anyway, first hand, i have had linux system writing corrupted packets on the the net [went away when ethernet driver was changed]. when we changed various things in bpf and syskonnect ethernet driver fleebsd was fine with our hacks, linux occasionally had issues (we didnt do too much research on what the problem was ... we just abandoned it ... and the problems seem to in part go away when we had faster processors and faster disk bus). i dont remember which file system it was, but one of them lost us some data and it didnt appear to be a hardware problem [was a while ago also... lately i havent been looking but havent casually noticed data loss at fs level]. i dont need to say anything about linux nfs server. admittedly these are rare, but they are in areas you expect perfection. a bigger problem is just general "weird behavior" under load [or sometimes even not under load]. linux does too many short cut things for "typical case" speed hacks. this can lead to your being out to sea when something goes wrong [e.g. when you look at a solaris crash dump, you have much better info than trying to figure out what happened in the linux case. this might partly be my better knowledge of solaris but in some cases the relevant info about the thread state, locks, watchdogs simply were not there] and also the system behavior often is sort of unusual under load [e.g. low free memory + high io, compared to FreeBSD and solaris (although when various large changes were made in solaris kernel algorithms for short periods i did see some performace issues)]. finally i dont like the way the memory-file system subsystem has been evolving. recently seen some problems in work environments with lots of (tcp) connections ... you get weird hangs on clients when the server drops packets ... admittedly this might have been fixable by throwing hardware at the problem or tweaking various para- meters (and this was on some HPC enviornments were we could not compare against solaris/bsd). YMWTGF: andrew hume HotOS linux suspect --psb \_ Our answer was much simpler than yours. After too many lost files, NFS problems, dropped packets, etc, etc, we simply stopped using Linux because it sucks. We didn't have the time to get into this driver vs that driver or what kernel patch might have helped or which NIC, etc. Linux = not ready for enterprise = out the fucking window. Staff time is more expensive than the value of possibly finding a solution to kludge Linux into working. The moment we switched to real OS's our problems just magically went away without hiring a team of Linux kernel developers. Linux is cute but their development philosophy precludes it's use in enterprise environments. Just FYI, I'm tossing around 20-30TB/month between various hosts. \_ Which OS did you switch to? FreeBSD? Solaris? \_ Yeah, especially now that Sun sells the X1 for under$1k. \_ I should have added: The system from which I run the ftp was OS X, which is a (free)bsd derivative. And I also noticed that the bad download had wrong modification time. It was set to be the day of the download, even though I have "preserve" on.

It looks like I need to "buy" Solaris only if I have multiple CPU's. Am I missing anything? \_ Say what? \_ It looks like you have to purchase a media kit and licenses separately. There are several media kits that differ by the amount of included printed documentation, value-added software, languages CDs, etc. I just ordered a Solaris 8 02/02 media kit with all software but no printed documentation for $75 and Solaris 9 FCS media kit for$95. Now, if you need to run it on multiprocessor machines, add the cost of license on top of that. As for the "free" version, it only includes the Solaris OS and no value added software. May be this is exactly what you need. Solaris 8 media kit includes some useful freebies like the iPLanet directory server with a license for up to 200,000 directory entries. Note that Solaris 9 ISOs are still not up for a free download.. \_ I think that you also get the vol mgr with the paid version \_ That was up to Solaris 7. Disksuite packages for Solaris 8 were included on the second Solaris software CD, although, hidden in a directory suspiciously called "EA". As of Solaris 9, the vol manager has been integrated into the OS, so you shouldn't even need to deal separate packages any more.
