nfs mount issue

MikeL_4 — Sun, 17 Feb 2008 05:24:28 GMT

I have a server that has an nfs mount to another server that was taken offline...

The remote server admin never informed us the server was being shutdown before and now our server is hanging looking for the nfs mounted file systems....

Is there any way to get these cleared short of a reboot ??

Hy, if you have 11.23 or 11.31 you can use the umount -f /nfs_mountpint.

If you have 11.11 you can try to stop the nfs client and nfs core processes(if you don't have any other nfs mounts).

You can do it by:

/sbin/init.d/nfs.client stop
/sbin/init.d/nfs.core stop

Try to umount it

/sbin/init.d/nfs.client start
/sbin/init.d/nfs.core start

Shalom,

You may try and configure the connection with autofs.

OR you can try this:

/sbin/init.d/nfs.client stop
/sbin/init.d/nfs.server stop
/sbin/init.d/nfs.core stop

/sbin/init.d/nfs.core start
/sbin/init.d/nfs.server start
/sbin/init.d/nfs.client start

That might help.

I have tried to stop the nfs.client, but it ust hangs, never shuts down... any way to force it down to free these mounts ?

Hello,

You are obviously using aging HP-UX 11.11.

Please refer to some good references:

in environment where the nfs server might go up/down sometimes, there is a place to consider using automounter rather than using fstab.
you'll get more flexible behaviour

Thanks, was trying to avoid a reboot, but I guess there isn't any other way...
