as root, do the following

# (mount partition as read only – allows fsck to work)

mount -oremount,ro /

e2fsck /dev/sda1

where / is the path to device you want to fsck, and sda1 is the device name (could be hda1, hda2, sdb3 etc)

then when done, do

mount -oremount,rw /
telinit

(here it will give you a number which is current run level, note it (debian is N 2)

then.

telinit 1; telinit 2

(where 2 is the number given to you in first telinit line)

How to specify some fsck cli params in this case?

I used “touch /forcefsck” which forced the system to check after reboot…fine
but on the subsequent boots still forces to check. I looked in root dir for the forcefsck file but it is not there….what then makes the system force to check? :(

Running fsck, by whatever means, will cause the mount counter to be reset to 0. Well, so long as it completes successfully. If fsck dies for some reason (like trying to run on a mounted or read-only file system, oops) then the counter is not reset.

As for running on fsck on the partition mounted on /home, that should automagically mount, and will be checked at that time; just do (no quotes) “sudo touch /home/forcefsck” if mounted and if not mounted, you can run it directly, if you can log in, that is. Get to root and just run it one the device: “sudo fsck /dev/sda6″ or whatever device it is.

Will performing a “shutdown -rF now” or a “touch /forcefsck ” at a specific date and time once a week prevent the “automatic fsck” that is forced by the ext2/ext3 partition parameters ?? (can be set by tune2fs ) – i mean.. will it “reset” the timeouts/deadlines if doing a force fsck manualy once a week so there will be no “surprise” when trying to reboot my server if needed ?? any positive experience on that?

thanks! sudo touch /forcefsck is a good way :)

There’s no need to use the touch command, “>/forcefsck” will do.

On RHEL 4, ‘shutdown -rF’ just writes /forcefsck anyway.

@dj:

Your ‘shutdown’ tip won’t work on many modern distributions, since they use Upstart instead of the old Sysvinit system.

Upstart has dropped many legacy commands that would be better done differently, in favor of a modern lean system.

‘touch /forcefsck’ is currently the most universal way.
