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

aix下面挂载linux文件系统，失败，如下代码

# mount 10.0.0.10:/Tbackup /back

mount: 1831-008 giving up on:

10.0.0.10:/Tbackup

vmount: Operation not permitted.

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

# nfso -p -o nfs_use_reserved_ports=1

Setting nfs_use_reserved_ports to 1

Setting nfs_use_reserved_ports to 1 in nextboot file

# mount 10.0.0.10:/Tbackup /back

#

ps:

5.2版本下执行：

nfso -o nfs_use_reserved_ports=1

5.2（含）以上执行：

nfso -p -o nfs_use_reserved_ports=1

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
