Blue Quartz & RAID

Your new server uses RAID-1 (mirroring). It provides for a level of redundancy should one of your new drives fail!

DO NOT INSTALL
if your running v3.5 or better of our installer!
Please use "yum update" to upgrade your RAID software. This is here for archival purposes ONLY!

RAID Doesn't Rebuild on 3.5?

RAID Tools integrates into Active Monitor so you will get notices about RAID status! It also includes the needed tools to rebuild raid without intervention! Simply replace your old drive, and reboot! It will rebuild automatically! You may need to put working drive on primary channel should your server not boot back up! Should you wish to test RAID before you put your box into production, this is how you would do it

RAID must already be setup and working before this package is installed!

How can I test RAID?

* This example assumes "sdb" is your 2nd drive. If it isn't, use "hdc".

First tell RAID your drives are faulty

/sbin/raidsetfaulty /dev/md0 /dev/sdb1
/sbin/raidsetfaulty /dev/md1 /dev/sdb2
/sbin/raidsetfaulty /dev/md2 /dev/sdb6
/sbin/raidsetfaulty /dev/md3 /dev/sdb3
/sbin/raidsetfaulty /dev/md4 /dev/sdb7
/sbin/raidsetfaulty /dev/md5 /dev/sdb5

Now tell RAID to remove it

/sbin/raidhotremove /dev/md0 /dev/sdb1
/sbin/raidhotremove /dev/md1 /dev/sdb2
/sbin/raidhotremove /dev/md2 /dev/sdb6
/sbin/raidhotremove /dev/md3 /dev/sdb3
/sbin/raidhotremove /dev/md4 /dev/sdb7
/sbin/raidhotremove /dev/md5 /dev/sdb5

You can check the status of RAID by doing;

cat /proc/mdstat

It should show you:

Personalities : [raid1] 
md1 : active raid1 sda2[0]
      4192896 blocks [2/1] [U_]
      
md3 : active raid1 sda3[0]
      2096384 blocks [2/1] [U_]
      
md5 : active raid1 sda5[0]
      1052160 blocks [2/1] [U_]
      
md2 : active raid1 sda6[0]
      1052160 blocks [2/1] [U_]
      
md4 : active raid1 sda7[0]
      12466304 blocks [2/1] [U_]
      
md0 : active raid1 sda1[0]
      104320 blocks [2/1] [U_]
      
unused devices: <none>

* Please note, your blocks may be different then shown here.

Now, you can reboot. Your RAID should rebuild itself!!. Or do it manually;

/etc/rc.d/init.d/mdchk

It should output the following:
