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

[Ilan Schwarts]

Hi all,
My setup is 2 nodes GPFS and 1 machine as NFS Client.
All machines (3 total) run CentOS 7.2

The 3rd CentOS machine (not part of the cluster) used as NFS Client.

I mount the NFS Client machine to one of the nodes: mount -t nfs
10.10.158.61:/fs_gpfs01/nfs /mnt/nfs4

This gives me the following:

[root at CentOS7286-64 ~]# mount -v | grep gpfs
10.10.158.61:/fs_gpfs01/nfs on /mnt/nfs4 type nfs4
(rw,relatime,vers=4.0,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.10.149.188,local_lock=none,addr=10.10.158.61)

Now, From the Client NFS Machine, I go to the mount directory ("cd
/mnt/nfs4") and try to set an acl. Since NFSv4 should be supported, I
use nfs4_getfacl:
[root at CentOS7286-64 nfs4]# nfs4_getfacl mydir11
Operation to request attribute not supported.
[root at CentOS7286-64 nfs4]#

>From the NODE machine i see the status:
[root at LH20-GPFS1 fs_gpfs01]# mmlsfs fs_gpfs01

I saw this thread:
https://serverfault.com/questions/655112/nfsv4-acls-on-gpfs/722200

Is it still relevant ? Since 2014..

Thanks !
