1)/vol/volnfs-sec=sys,rw,anon=0,nosuid
At this point, all NFS client root users can change file and folder permissions using Chmod. With the anon=0 parameter, the root=192.168.10.90:192.168.10.91 parameter is superfluous (because anon grants root access to all NFS client root users on NetApp).
2)/vol/volnfs-sec=sys,rw,anon=65535,nosuid
Setup anon=65535 can do this, the root user of NFS client cannot read and write, but the normal user of NFS client can read and write.
Note:
1) The NFS client can mount the volume on the storage, only to see if the RW (read and write) permission is given, regardless of root permission. have root permission, no rw or RO permissions, still cannot mount on the NFS client.
2) When RO,RW does not add an IP address, it means that all NFS clients are allowed.
3) When running chmod on the NFS client, both the root and the RW permissions are stored.
