Q. How do I mount NFS filesystem twice in two different dirs on same Linux client?

NFS Server : nfsserver:/data

Mount to dirs /home/data and /backup

A. You will not able to do that. However mount command has bind option to remount part of the file hierarchy somewhere else.

Procedure

First mount to /home/data
# mount -t nfs4 nfsserver:/data /home/data
Now bind /home/data to /backup
# mount --bind /home/data /backup
# ls /backup /home/data

Read man page of mount command for more information:
$ man mount

Mr Singh,
Try IBM DeveloperWorks LPI Tutorials. An absolute must in my opinion.

Thanks for this – I was getting “stale NFS file handle” because I had mounted the filesystem twice. Clearly I should not have done so!

Do you know if there is anything that causes issues with bind when using a CIFS mount?

I have a few directories that I mount that way, but after a while, it starts listing everything in them (the bind mounted ones) as directories. The original CIFS mount is still fine though.
