Hi, This was my fstab line : gluster-node3v:/dev /data nfs4 noatime,_netdev,auto 0 0 I tought it was the way to mount nfs v4.0 but now, I don't think so ! So I changed it to : gluster-node3v:/dev /data nfs nfsvers=4,noatime,_netdev,auto 0 0 If I look at the ganesha (niv_debug) logs, now I see it is mount in nfs v4.0 instead of v4.2. I will first try with this and ask for help if it fails again.

Pkt trace may help in further debugging. Also we haven't tested v4.1 and v4.2 protocols extensively with glusterfs. Could you please check the behavior with v4.0 protocol mount.
