Question about EXT3 error messages in /var/log/messages

[Mark Cuss]

Hello list

I've been having the following error messages pop up in my kernel log:

Apr 12 04:08:09 hal kernel: EXT3-fs error (device md(9,2)): ext3_readdir:
bad entry in directory #2670595: rec_len %% 4 != 0 - offset=0,
inode=827218527, rec_len=20275, name_len=73
Apr 12 04:08:14 hal kernel: EXT3-fs error (device md(9,2)): ext3_readdir:
bad entry in directory #2670596: rec_len %% 4 != 0 - offset=0,
inode=861103477, rec_len=95, name_len=95
Apr 12 04:08:17 hal kernel: EXT3-fs error (device md(9,2)): ext3_readdir:
bad entry in directory #2670597: rec_len %% 4 != 0 - offset=0,
inode=1601531495, rec_len=30819, name_len=120
Apr 12 04:08:20 hal kernel: EXT3-fs error (device md(9,2)): ext3_readdir:
bad entry in directory #2670598: rec_len %% 4 != 0 - offset=0,
inode=1634890872, rec_len=29795, name_len=111
Apr 12 04:08:32 hal kernel: EXT3-fs error (device md(9,2)): ext3_readdir:
bad entry in directory #2670599: rec_len %% 4 != 0 - offset=0,
inode=1951614277, rec_len=12337, name_len=95

I've done some searching and talked to some people on another mailing
list...  I can't seem to figure out which device these errors occur on...
I'd been told that the "device md(9,2)" ID indicates major 9 and minor 2,
and I've also been told that the 9 is the SCSI channel once 8 is subtracted
from is (so, 1 in this case), and that 2 is the SCSI Id of the offending
device in that channel.

So, I'm a little lost here.  I figured the experts here could let me know
how to map the reported ID numbers to a physical disk or RAID device.

Thanks in advance!
