3/15  Why doesn't soda use a raid for its disks?  It seems kind of
      wasteful to mirror each drive (and only on a nightly basis).
      \_ want to buy CSUA a reasonable raid card?  --jon
         \_ what about software RAID, are there reasons for not doing it?
            \_ yes, they all suck for anything but striping/mirroring
                 well unless you pay for something real, like VERITAS
               \_ striping and mirroring. Isn't this what soda needs to do
                  with the disks?
                  \_ the argument above was that mirroring was wasteful.
                     the common alternative is raid-5.  but software
                     implementations of raid-5 in SW tend to suck --Jon
                     \_ right, but wouldn't it be better to use software
                        raid for mirroring the disks instead of nightly
                        rsync?
                        \_ Yes but this isn't a professionally administered
                           system.  -disk management guy in real world
         \_ what is a "reasonable" raid card? If its in the $200
            price range I'd be willing to buy the card and donate
            it to the csua. - alum

5/6     http://goo.gl/KiIMT (shortened link from http://HP.com)
        seems like I get these every 6 months or so from HP.  Do all drives
         have these kind of issues and I only see the ones from HP because
         they are diligent about reporting/fixing these issues?  Or do they
         suck?   (It's not actually their drives so...)  Also, do I really
         need to bring down my production infrastructure and fix all this

1/4     I want to test how my servers behave during a disk failure and
        a RAID reconstruction so I want to simulate a hardware failure.
        How can I do this in Linux without having to physically pull
        a drive? These disks are behind a RAID card and run Linux. -ausman
        \_ According to the Linux RAID wiki, you might be able to use mdadm
           to do this with something like the following:

9/13    Thanks to Jordan, our disk server is no longer virtualized. Our long
        nightmare of poor IO performance should hopefully be over. Prepare for
        another long nightmare of poor hardware reliability!

        Just kidding! (I hope)
        In any case, this means that cooler was taken out back and shot, and

2/18    Why does the system seem so sluggish lately?
        \_ Slow NFS is basically always the answer. --toulouse
        \_ Any truth to the rumor that soda will be decommissioned this summer?
           \_ Absolutely none. Soda might go down temporarily while disks are
              reorganized and stuff so soda doesn't suffer from such shitty
              performance nearly as much, but no, we've gotta maintain NFS and

        Anyone have a recommendation? Thx.

10/27   I just read an article that Facebook had moved their database
        to all SSD to speed throughput, but now I can't find it. Has
        anyone else seen this? Any experience with doing this? -ausman

8/20    When I use rsync to backup, it's pretty cool except in cases where
        I rename a directory name from the source. Rsync will just do
        a plain copy. Is there a program that'll detect renaming of
        directories (by checking for children files), or at least
        move them to a dated directory?
        \_ Not related but beware of using rsync as a backup tool.

7/28    Does it make sense to defragment disks on VMWare? My 80GB disk
        on VMWare isn't really using 80GB, it just uses what it needs.
        Will defragment do anything to it?
        \_ If you want to speed up disk operation in your VM, it's best to
           defragment the disks in your VM, then defragment the disk on your
           host machine where the VM files are.

7/24    Firefox 3.5.1 on MacOS is a piece of crap. It crashes ALL THE TIME.
        It has crashed 3 or 4 times on me in the last hour, and not on
        the same pages either. The new Yahoo! home page also sucks ass.
        \_ os x keeps trashing my raid disk: '11 hours to rebuild. have fun
           with the kernel IO subsystem running like shit until then".
           Worthless piece of shit.
