[gpfsug-discuss] How to use nfs4_getfacl (or set) on GPFS cluster

On my test setup (rhel7.3 nodes gpfs cluster and rhel7.2 nfs client); I can
successfully read nfsv4 acls (nfs4_getfacl).

Can you please try following on your setup?

1> capture network packets for above failure and check what does nfs server
return to GETATTR ?
=> tcpdump -i any host 10.10.158.61 -w /tmp/getfacl.cap &; nfs4_getfacl
mydir11; kill %1

2> Also check nfs4_getfacl version is up to date.
=> /usr/bin/nfs4_getfacl -H

3> If above doesn't help; then make sure you have sufficient nfsv4 acls to
read acls
(as per my understanding; for reading nfsv4 acls; one needs EXEC_SEARCH
on /fs_gpfs01/nfs and READ_ACL on /fs_gpfs01/nfs/mydir11).
=> mmgetacl -k nfs4 /fs_gpfs01/nfs
=> mmgetacl -k nfs4 /fs_gpfs01/nfs/mydir11

Thanks,
Chetan.
