NFS4 - Mounting multiple subdirs

Solution 1:

Figured out the problem. Because I set /mnt/nas as fsid=0, that means that clients mounting subdirectories no longer need to reference the entire path, only the child subdirs (relative pathing).

Change this:

$ -> mount -v -t nfs4 nas.vpc1.j1n.us:/mnt/raid/nas/file/perm /mnt/nas/store/file/perm/
$ -> mount -v -t nfs4 nas.vpc1.j1n.us:/mnt/raid/nas/mail /mnt/nas/mail/

To this

$ -> mount -v -t nfs4 nas.vpc1.j1n.us:/file/perm /mnt/nas/store/file/perm/
$ -> mount -v -t nfs4 nas.vpc1.j1n.us:/mail /mnt/nas/mail/

Notice that in the 2nd set of commands the parent path /mnt/raid/nas is missing from the server:/path section of each command.
