cannot umount /tmp

[Larin]

I have had a problem.

There is a mounted fileset in /tmp
# df -k /tmp
Filesystem 1024-blocks Used Available Capacity Mounted on
tmp_domain#tmp 17779680 55044 17713952 1% /cluster/members/member0/tmp

Now, I cannot umount fs
# umount /tmp
/cluster/members/member0/tmp: Device busy
But
# fuser -c /tmp
/tmp:

any ideas?
How can I force umount?

[Ivan Ferreira]

member0 is not a cluster, so, there may be a kernel process that is not listed by fuser.

You can try the -f option, but I will suggest booting in single user mode instead.

/tmp is used by many commands for temporary data. Why would you want to unmount it?

Try '-d' option of fuser to view the files that are deleted but still used by commands.

Hi,

remove the fileset from /etc/fstab and reboot.

greetings,
