Sure, the mount command is:

sudo mount [NASIPADDRESS]:/mnt/DataPool1/TestRootStore/TestSubStore/TestDataStore3/TestDataStore4 /nfs/TestDataStore

And here is the NFS export page:

Ok I’ve managed to get this to work. Like you I was getting the same behaviour but it seems you need to add the everyone group with traverse rights on DataPool1/TestRootStore/TestSubStore/TestDataStore3 otherwise it gets blocked when trying to traverse.

Give that a shot.

Thanks very much, I added the ACE for the everyone group to both of the NFS folders and I can now mount both folders and see full RW permissions and NFS4 version etc from the client mount command.

I think I need to find some documentation on permissions and ACLs as they are still a mystery to me…

Hey that’s great to hear. I think you’ve stumbled across a fairly niche case so don’t be so hard on yourself.

Sorry I’ve been traveling the last couple of days so only had time to sit down and test this morning.

Credit to @awalkerix for planting the everyone group pearl of wisdom as that lead me down the right path.

Thanks for raising as I’m sure this will be very helpful to future forum readers.

For info it should only be necessary on the parent dataset unless you plan on creating more sub-datasets within the last.
