Hello,
I hope this is the right list to come to, apologies if the question
should be inappropriate.
I administer a machine running Redhat 7.1 with the 2.4.2-2 kernel. I
have recompiled the kernel applying all (then) current reiserfs patches
and have been been running Reiser FS on it since June. I set the disk up
to contain identical partitions in ext2 and Reiser, so there's a
/boot,/,/home,/usr partition in ext2 and a /,/home,/usr partition in
Reiser.
Recently one of the users had a problem with Gnome not starting up and
(Windows-reflex) hit the reset button. The machine didn't reboot
normally though and I only got it running again by switching to the
ext2-partitions. This is what /var/log/messages say about the first
attempted reboot onto Reiser (Rohan is the name of the machine,
/dev/hda9 is the /usr partition under Reiser):

Upon doing a reiserfsck on the /dev/hda9 I get:
reiserfs_open: bread failed reading block 16
reiserfs_open: neither new nor old reiserfs format found on /dev/hda9
reiserfsck: --rebuild-sb may restore reiserfs super block
So my guess is that the superblock on hda9 was damaged somehow? My
question, should I do reiserfsck --rebuild-sb or first try to determine
further what caused this error? Anywhere else I should look?
Thanks in advance for any help,
Marc
