If its any consolation, I get this on a working system where hda is the
only drive:

r...@box:~# fuser -u /dev/hda1
r...@box:~# fuser -u /dev/hda2
r...@box:~# fuser -u /dev/hda

That is no output, although the machine is definitely being used.

But:

r...@box:~# lsof /home/chrisb
COMMAND  PID   USER   FD   TYPE DEVICE  SIZE  NODE NAME
zsh 3430 chrisb  cwdDIR3,1 20480 16312 /home/chrisb

vim 7487 chrisb  cwdDIR3,1 20480 16312 /home/chrisb

etc ...

Dear All
I have an Linux server that gets problemy from sudden power cut . I need to
run fsck in single user mode so I issued "#init 1" on the server . At the
server prompt , to serialize the fsck on the intended file system , I first
tried to unmount the intended file system and then issue the fsck (as the
following) :
#umount /dev/hda2
#fsck -s -a /dev/hda2


Is this the root partition?


But the server returned "Device Busy" . So I checked its status under "fuser
-u /dev/hda2" but no process recorded for it . Can you please do me favor
and let me know how can I force it as unmount to be able to try for safe
fsck on it ?


Which partition is this?

How about running "tune2fs" to force a fsck after next boot?

Dear Niu
With many thanks for your reply , I tried to force fsck after reboot as the
followings :
#cd /
#touch /forcefsck
#reboot
Can you please do me favor and let me know if this is the same as your
proposed procedure (since I am not familiar with your tune2fs and its usage)
?
