Re: File system error (power outage)
hi ya francisco
if it gives you that "WARNING" ... do NOT e2fsck a mounted filesystem
what you probably need to do ...
assuming you have the following partitions
when it comes up and asking/telling you to run fsck manually
- you should answer "y" to any questions it ask
unless you know how to fix it without the e2fsck ap
- if you get too many (hundreds) errors on sequential inodes
than that partition is toast ... re-format it and restore from
# there is no guarantee that this will fix the problem but
# you dont have much choice ..
# these same problems (semi-corrupted disk) will occur if you
# hit the power or reset switches ( not just from power outage )
--- to fix things up:
- NOTE ... fix / last ( and do it after mounting it "read-only"
NOTE ... do NOT e2fsck the swap partitions
- fix /tmp
root# e2fsck /dev/hda2
- fix /var
root# e2fsck /dev/hda3
- fix /usr
root# e2fsck /dev/hda5
- fix /home
root# e2fsck /dev/hda6
- now fix / -- Important to use the right -o options
root# mount -o ro,remount /dev/hda1 /
root# e2fsck /dev/hda
-- reboot and you should be happy camper
