Hi All,

I'm facing an issue while trying to unmount a remotely mounted file system, strangely it's not even getting mounted, Kindly find the reply messages.

Mounting error msg

Code:

nfsmnthelp: 1831-019 <Server host>: Cannot mount a file system that is already remotely mounted.
mount: 1831-008 giving up on:
Cannot mount a file system that is already remotely mounted.

Unmounting error msg

unmount: 0506-347 Cannot find anything to unmount.

If any one knows please help.

Please use code tags next time for your code and data.

I would start by looking at the output of

Code:

mount

command and

Code:

cat /etc/filesystems

Hi,

When i check at the provided path, I see a number of Process IDs which pertain to a number of SAP and ORA processes, I cant kill the processes as it's a active in use server.

Is there another way of doing this?

Ok will do that thanks !!

To be on the safe side, umount it when you get a downtime for the applications on it.
While the processes are still using this mount, are you sure you may umount it? Just out of curiosity and to make sure.
If you get a downtime for the applications and can umount it, you may also check /etc/rmtab if the entry is still in there, as this is maintained by mountd, to remember mounts after a crash and sometimes problems can occure if it is still in there but not needed anymore.

Hi,

I basically need to mount this file system as my Offline backup is fired to this fs.I have created a cron script which created a file into this file system where the savevg backup is stored. As this FS is neither getting mounted nor unmounted my backups are failing.

This is just a try to check if i manually unmount this filesystem, it may mount through the script and the backup will complete.

Infact i was thinking about the same solution that you have suggested, but i was a little hesitant as I'm a little new to this. If you feel like suggesting any thing, I would be more that happy to look into it.

just mount the filesystem under another path and adapt your backup scripts till you get the downtime

This sounds a bit confusing, so I'll try to reword your problem.
You try to mount a nfs-filesystem located on a remote server. The mount command already fails with the errormessage "Cannot mount a file system that is already remotely mounted". The remote filesystem is not mounted.
When you try to umount the (not mounted) remote filesystem you get the message "0506-347 Cannot find anything to unmount".
Is this correct?

A filesystem that is not mounted can not be unmounted and the error will not show up when you succeed in mounting before trying to umount.

What type of filesystem is this filesystem on the remote server? Is it possible that this remote server mounted that filesystem as a remote nfs-share itself?
