Title: Raidmonitor Help
Post by: Derek L on January 14, 2004, 07:18:32 PM

Hello,

Sorry to beat a dead horse, (and yes, I did search the forums), but I need some help interpreting a Raidmonitor alarm:

Personalities : [raid1]
read_ahead 1024 sectors
md2 : active raid1 hda3[0](F) hdc3[1]
      264960 blocks [2/1] [_U]
     
md1 : active raid1 hda2[0](F) hdc2[1]
      79666240 blocks [2/1] [_U]
     
md0 : active raid1 hda1[0] hdc1[1]
      104320 blocks [2/2] [UU]
     
unused devices:

Last known good configuration was:

Personalities : [raid1]
read_ahead 1024 sectors
md2 : active raid1 hda3[0] hdc3[1]
      264960 blocks [2/2] [UU]
     
md1 : active raid1 hda2[0] hdc2[1]
      79666240 blocks [2/2] [UU]
     
md0 : active raid1 hda1[0] hdc1[1]
      104320 blocks [2/2] [UU]
     
unused devices:

My interpretation is that partitions 2 and 3 on hda have failed, and I need to hottadd them back to the array like so...

/sbin/raidhotadd /dev/md2 /dev/hda3
/sbin/raidhotadd /dev/md1 /dev/hda2

...and then wait for the re-sync and run raidmonitor -iv. Does this sound right? If the re-sync doesn't work, then I need to replace hda?

Thanks in advance,

Derek

Absolutely correct.

Much obliged. After my backup finishes, I'll give it a whirl.

It turned out that it was hdc, not hda. That seems very counter-intuitive to me from what the alarm says. Can anyone explain to me how the alarm message indicates a problem with hdc? Or is it in error?

Thanks,

Derek
