Hello
During the power failure my file system was probably corrupted. But the
problem is strange for me. Here is fsck:
# fsck
** /dev/rwd0a (NO WRITE)
** Last Mounted on /
** Root file system
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames

So if I understand correctly, some files are corrupted and all partitions
are in read-only status. Interesting is that I can write files to all
partitions.
Here is a mount output:
/dev/wd0a on / type ffs (local)
/dev/wd0d on /home type ffs (local, nodev, nosuid)
/dev/wd0e on /usr type ffs (local, nodev)
/dev/wd0f on /var type ffs (local, nodev, nosuid)
Because file owned by mysqld are on /var I decided to unmount /var repair it
by fsck and then mount it again. But it is really strange.
# umount -f /dev/wd0f
# fsck /dev/wd0f
** /dev/rwd0f
** File system is clean; not checking
it means that /var is ok, i rather forced fsck but same result:
# fsck -f /dev/wd0f
** /dev/rwd0f
** File system is already clean
** Last Mounted on /var
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups
15024 files, 2102173 used, 4192338 free (4778 frags, 523445 blocks, 0.1%
fragmentation)
Now I performed fsck for all mount points again and corrupted files have
gone:
# fsck

** Phase 2 - Check Pathnames

I rebooted but fsck shows same problem as before. All mount point are
read-only, they are not marked as clean and I see corrupted files.

This situation is wired for me and I do not understand it. Can somebody
help?
Thanks a lot
