How to unmount the NFS. Please help.

[yulianto piyut]

hi almond,

did you checked the source of nfs mounted? I think, you must check the source first. If at the source, the shared directory not mounted, you must mount it (restart nfs daemon) and than try to umount the directory at client.
to restart nfs daemon:
# /sbin/init.d/nfs.server stop
# /sbin/init.d/nfs.server start

Hi Almond,

Try
#fuser -au /file system name

It will shown the user who are using that file system.

Kill the user who are accesing the the file system
# kill -9 processesid or userid.


#cd /

#umount /filesystem name

Hi again,

why you don't try to give server A a 'server B' again? Change the ip address in /etc/hosts so server A can see server B again - or define any client you don't use at the moment and configure it like server B was before you changed it - OR undo the changes at server B.

When the mount is established again, you can unmount without problems. Then (after /etc/fstab is changed) you can change back.
