Hello,
I have a cluster with 2 nodes that I want to access using NFS, there is no firewall between the server.
I'm using gluster 3.9.0
The volumes mount correctly on a client machine, even if I get a strange "portmap query retrying: RPC: Program not registered"
[root@nf1 ~]# mount -vvv -t nfs -o nfsvers=3,rw gluster-nfs-a:/replicated-data /export/replicated-data
mount: fstab path: "/etc/fstab"
.........

gluster-nfs-a:/replicated-data on /export/replicated-data type nfs (rw,nfsvers=3)
When I try to lock a file on the client with something like:
flock -x -w 10 100 file (...)
the lock doesn't work and I get those line on the server nfs.log:

Why the server I'm connected is trying to connected to the replica: 0-replicated-data-client-2: server 10.4.0.33:49159 ?

Is here talking about the client trying to lock a file in the volume, or actually the other replica server on 10.1.0.33 ?
Any idea?
Thanks,
