Dear all,
I am running raidtools 0.90.990824-5 on a mingo-B1-patched 2.2.14 for
quite some time. Now a few days ago the machine just froze (no keyboard,
no login, no remote login, ping worked, that's all) and had to be
resetted. It came up fine, reconstructed etc. but there is really not a
single hint in the logs for the freeze. Now I 'could' live with that but
two days later I got ext2fs errors on one of the raid0 partitions. Things
like the following:
Mar 15 01:29:46 kludge kernel: EXT2-fs warning (device md(9,3)):
ext2_unlink: Deleting nonexistent file (159), 0
Mar 15 01:49:47 kludge kernel: EXT2-fs warning (device md(9,3)):
ext2_unlink: Deleting nonexistent file (160), 0
Mar 15 06:28:11 kludge kernel: EXT2-fs warning (device md(9,3)):
ext2_free_inode: bit already cleared for inode 150
I did a reboot and checked and cleaned up the filesystem. Now I have two
problems:
- there are corrupt files left that I cannot move/remove by normal means
(i.e. rm/mv and a unlink(2) call did not work)
- I still get ext2-fs warnings!
Here are some of the files:
kludge:/var/spool/squid/03# find . -not -type d -ls

And here are recent warnings:
Mar 17 09:06:06 kludge kernel: EXT2-fs error (device md(9,3)):
ext2_readdir: directory #198 contains a hole at offset 20480
Mar 17 09:06:16 kludge kernel: EXT2-fs error (device md(9,3)): empty_dir:
bad entry in directory #198: rec_len is smaller than minimal - offset=4096,
inode=0, rec_len=0, name_len=0
Anyone got an idea how to get rid of both? I have attached the relevant
proc-info at the end. The machine is a dual-pIII with an onboard adaptec
AIC-7890/1 (AIT tape connected) and a dual-channel AHA-394X with two
chains of 3 IBM disks each. The network card is a 3com905b. I guess I
should move that to use an extra interrupt. But that should not be the
source of the problem since the scsi-controller is the one the tape is
connected to? Hmmm, thinking over that again. I only recently started to
use the tape drive heavily. So this could be the cause?!
