Symptoms

nfs4_getfacl hosts

Operation to request attribute not supported.

nfs4_editfacl hosts

Operation to request attribute not supported.
Failed to instantiate ACL.

 

Cause

The client did not mount the export with NFS4.

10.32.xxx. xxx:/nfsv4fs on /nfsv4fs type nfs (rw,relatime,vers=3,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.32.106.149,mountvers=3,mountport=1234,mountproto=udp,local_lock=none,addr=10.32.xxx.xxx )

# nfs4_getfacl nfsuser
Operation to request attribute not supported.
# nfs4_editfacl nfsuser
Operation to request attribute not supported.
Failed to instantiate ACL.

 

Resolution

The fix is to unmount and mount as NFSv4 on the client side.

# umount /nfsv4fs
# mount -o vers=4 10.32.106.149:/nfsv4fs /nfsv4fs
# cd /nfsv4fs
# nfs4_getfacl nfsuser
A::OWNER@:rwaDxtTnNcCy
A:g:GROUP@:rxtncy
A::EVERYONE@:rxtncy

Also ensure that the idmap.conf matches the NFSv4 domain of the server (server_nfs server_x -v4) and the NFS server/DM can resolve the user either by LDAP/NIS/Local files.
