Question

When nfs mounting from a Linux NFS server, customer gets the following

error:

vmount: operation not permited

Answer

--------------------------------------------------------------------------------

Environment

AIX versions 4.x and 5.x

Sometimes Linux NFS servers will do port checking and require that the NFS client use a reserved port.

nfso -o nfs_use_reserved_ports=1

If the mount is going to be permanent, then the change needs to survive across a reboot. The nfs option must be changed permanently. On AIX 4.x and 5.1, the command above should be added to the startup scripts (possibly /etc/rc.nfs). On AIX 5.2 and above, the change can be made permanent by adding the -p flag.

nfso -p -o nfs_use_reserved_ports=1
