NFSv4Support attribute configuration
This sample configuration is for NFS when the NFSv4Support attribute is 1. Note that the share test_share0 has fsid = 0 in Options attribute. This indicates that /home/export is root of all the exports. The client needs to mount only this root filesystem instead of mounting all shares individually.
The syntax is:
mount -t nfs4 <server>:/ <mountpoint>
Note that path after colon(:) is always /
Also note that all the filesystems other then the root filesystem should have the nohide option set in Options attribute of share resources. Set the nohide option so that authentic clients can seamlessly move through the tree of exported filesystems just by mounting the root filesystem.
