NFS mount results in "vmount: operation not permitted" error

Technote (troubleshooting)


Attempts to mount a remote file system from a Linux NFS server results in the error "vmount: operation not permitted".


Unable to mount the remote file system.


root@lpar3:/ # mount /mnt
mount: 1831-008 giving up on:
vmount: Operation not permitted.


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


AIX versions 4.x and 5.x.

Resolving the problem

Use a reserved port in the mount command:


root@lpar3:/ # nfso -o nfs_use_reserved_ports=1
Setting nfs_use_reserved_ports to 1            
root@lpar3:/ # mount /mnt

Note: To make this setting permanent, use the nfso -p switch or add it to /etc/rc.local.
