Fsck

[bam]

Is there a way to run this from command line, tried Meanies instruction, didnt work for the 3100, kept "bouncing me out" so I just reset.

[lardman]

Yes.

fsck /dev/whatever-device-you-want-to-check

[bam]

but its not safe to run fsck on a mounted file system, right?

[lardman]

That's right, in fact it's actually not possible afaik.

Do 'umount /dev/whatever-device-you-want-to-check' first

(you may be able to get away with 'umount /mnt/whatever-mountpoint' actually)

How about a filesystem that doesn't want to be unmounted,
my large /dev/hda2 on pdaXrom needs fsck gravely,
but the full check is not done from the maintenance menu and
when I try after booting, there are services running which prevent unmounting,
how do I enter a lower runlevel on the zaurus?

OK, found a solution, from [a href=\"http://www.eleves.ens.fr/home/leurent/zaurus.html]http://www.eleves.ens.fr/home/leurent/zaurus.html[/url],
thanks Gaëtan:

"You will need to kill the apps using this partition first, you can find them fuser -m /dev/hdc3 and kill them with kill -9 $PID where $PID is one the numbers returned by fuser."

This is getting a little off topic... but how do I know what processes the returned numbers are... can I pipe the command to show me what those processes are?

even after you kill all the processes, there still may be some inodes being locked which you can unlock using losetup -d /dev/...
