file system, kernel or hardware raid failure?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I had a busy mailserver fail on me the other day. Below is what was
printed in dmesg. We first suspected a hardware failure (raid controller
or something else), so we moved the drives to another (identical
hardware) machine and ran fsck. Fsck complained ("short read while
reading inode") and asked if I wanted to ignore and rewrite (which I
did). 

After booting up again, the problem came back immediately and root was
remounted read only. We moved the data from the read only drive to a new
machine. While copying the data, we got this message from time to time
(on various files): "EXT3-fs error (device dm-0): ext3_get_inode_loc:
unable to read inode block - inode=22561891, block=90243144.

I need to find the cause(s) of the problems. So far I have these
questions/concerns:

- Kernel bug? (This is Ubuntu 8.10 with 2.6.27-7-server)
- Filesystem bug/failure?
- Did the RAID controller fail to detect a failing drive? This is an
  Adaptec aoc-usas-s4ir running on a Supermicro motherboard.

I suspect that one of the drives (RAID 6 btw) has failed, but I'm not
sure what to do from here.

Any ideas? Thanks in advance.
