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
AIX下挂载Linux文件系统nfs-vmount: Operation not permitted
