Stale NFS mounts

Hi all,

I'm using NFS on my laptop to export some of the file system to my
desktop. When I run showmount -a hostname on the desktop I'm getting a
number of stale mounts in addtion to the active ones. How can I get rid of
the stale mounts?

That's because your nfs code was compiled using a non-airtight container
class. If you use an airtight version then they won't go stale.

Sorry, it's been one of those days today...

Try using "umount -f /path/to/mount" to clear them.

Yes. He should clear the stale mounts out of the cupboard and make new
ones. ANd next time DO use a proper vacuum to clear up with.

You're just annoyed at yourself for forgetting to tell him to keep
locking the container class after using it.

One thing to keep in mind with NFS is that its always a good idea to
using some time-syncing mechanism, such as NTP, althought I don't know
if that't the cause of stale handles.

You might also try using lsof to see if anything is using that file.

Also, check that you've used exportfs -av on the server.

Hosts that have mounted your exports are tracked in rmtab, whose
location varies from distribution to distribution. On my RH machine
it's at /var/lib/nfs/rmtab. The mountd man page says it's supposed to
be at /var/state/nfs/rmtab. YMMV

rmtab is described by the man page as "mostly ornamental" and gives
reasons you may find enlightening (and one of which you've already
discovered).
