problem with umount
Subsystems (2)
Hi ,
I have suse installed(2.6.5-7.109.12-smp)
installed on my machine.umount version 2.12 If i mount filesystems and export them
and if nfs client does some processing on filesystem , server side sometime fails to unmount it.
But if client stays without doing any processing , everything works fine.
I tried using umount <filesystem> -O -l
but this does not work though man pages
say that even if there are reference to filesystem , it will be unmounted and later do required cleanup.
As problem arises only when nfs client does some processing on filesystem , there must be problem in nfs.(must not be cleaning up all references) I have read previous thread on " forcing umount " Have anybody else faced the same problem ? Is there any fix for this ?
thanks,
kiran

-O options
Indicate that the actions should only be taken on file systems with the specified options in /etc/fstab. More than one option type may be specified in a comma separated list. Each option can be prefixed with no to specify options for which no action should be taken.
AFAIK, there is no "-l" _mount_ option, so it is extremely unlikely that your NFS-mounted filesystems are listed in /etc/fstab as using it. You're better off trying with "umount -l /filesystem".
Better still, fix your init scripts so that they kill whatever process it is that is still using the NFS partition and causing the regular "umount" to fail: *NIX does NOT allow you to unmount partitions that are *in use*.
Cheers,
