10/15  Do hardware raid drivers exist for linux yet?  url, if available
       (yes, I can search, but Im lazee :) )
        \_ http://www.redhat.com
           \_ boy, looks like you are lazy too; i was looking for something
             a little more specific :)
                \_ then go to http://www.redhat.com and SHUT THE FUCK UP
       \_ http://linas.org/linux/raid.html
          But this may not be exactly what you are looking for. -- jsjacob
          \_ This is a nice start.  Thanks!
       \_ I would think it would depend on WHICH HARDWARE you were using.
        \_ If the RAID implemntation is truly in hardware, shouldn't the
                linux machine be able to access it as just a regular
                scsi disk?
                \_ I was referring to those PCI RAID cards ive seen around.
                  That is hardware raid, but you will need drivers for those.
                  Also, even if it is an external hw raid, you might have
                  some problems.  For example,  you can't boot a solaris
                   box off an _external_ hw raid (well, atleast the ones
                    Ive got).  Once you get by the boot, then, yes, a hw
                    raid drive should just look like a scsi device.

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!

2/14    You sure soda isn't running windows in disguise?  It would explain the
        uptimes.
        \_ hardly, My winbox stays up longer.
        \_ Nobody cares about uptime anymore brother, that's what web2.0 has
           taught us.  Everything is "stateless".
           \_ You;d think gamers would care more about uptime.

7/22    Playing with dd if=/dev/random of=/dev/<disk> on linux and bsd:
        2 questions, on linux when <disk>==hda it always gives me this off
        by one report i.e. Records out == records in-1 and says there is an
        error. Has anyone else seen this?  Second, when trying to repeat this
        on bsd, <disk>==rwd0 now, to my surprise, using the install disk and
        selecting (S)hell, when I try to dd a 40 gig disk it says "409 records

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.

In fact, RAID is just one part of an overall data availability architecture. RAID, and some of the complimentary storage technologies, are reviewed below. RAID, short for Redundant Array of Inexpensive Disks, is a method whereby information is spread across several disks, using techniques such as disk striping (RAID Level 0) and disk mirroring (RAID level 1) to achieve redundancy, lower latency and/or higher bandwidth for reading and/or writing, and recoverability from hard-disk crashes. Over six different types of RAID configurations have been defined.
