"permission denied" error when trying to mount an NFS filesystem

[Michael Campbell]

An NFS filesystem was umounted and then expanded on the remote server. When I try to mount it again i'm getting a "permission denied" error.
Does anyone have any ideas as to why this would be? Thanks

Hi,

check /etc/exports at the NFS server and run

exportfs -a

filesystem is in /etc/exports
ran exportfs -a
tried to mount the filesystem again. The error is now

nfs mount: mount_nfs: mount: /pmsprod: Device busy

I ran fuser -fu on the remote server for that filesystem but it doesn't show anyone using it.

Hi,

Try unmount /pmsprod and then mounting it again.
Also you could try fuser as follows:
fuser nfsserver:[exported filesystem]

Good Luck

Also, you could try running showmount -e to show all the filesystems being exported by the server and to whom. This will tell you if you have permissions to mount the filesystem from the server.

Thanks folks, problem solved. There was actually some root processes running on the local directory where the filesystem was to be mounted.
I killed them and tried to mount it again, et voila!
