aix mount "vmount: operation not permitted" Error From Linux NFS 转载

When nfs mounting from a Linux NFS server, customer gets the following error: vmount: operation not permited

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

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

实际运用：

# mount 192.168.0.70:/tmp /mnt/tmp
mount：1831-008 放弃：
192.168.0.70：/tmp
vmount: 操作不允许执行。
# nfso -p -o nfs_use_reserved_ports=1
正在将 nfs_use_reserved_ports 设置为 1
正在 nextboot 文件中将 nfs_use_reserved_ports 设置为 1
# mount 192.168.0.70:/tmp /mnt/tmp
# ls /mnt/tmp
