Hi,
I've got serious problems with my system partition /dev/md0 (RAID1).
It has a journal. Recently I did a read-only e2fsck on it and got a
huge bunch of errors. Till a next reboot everything seemed ok. During
the next reboot, e2fsck tried to make a disk check but said that
there are many errors and that I have to do it on my own. So I
rebooted to single mode and did a e2fsck on it. It tried to repair
many and many errors and the result was that the system partition
was badly damaged. E2fsck did the check three times until there
were no errors. So I rebooted back to normal and recovered the
system from backups. When everything was done I rebooted back to
single mode to do e2fsck one more time (read only). The same bunch
of errors. So I rather did not the real test. I rebooted back with
those errors and now I'm gathering information...
Is it possible that the ext3 is somehow permanently damaged?
Is it possible that the problem is the raid?
Some of the errors:
Illegal block #12 (2150986755) in inode 1884. IGNORED.

etc etc etc
AND THIS is interesting. These are kernel messages during the test:

...
I have also RAID1 on /dev/md1 (data disk) without any problems.
Thanks for ANY information.
