[Gluster-users] Fwd: nfs-ganesha HA with arbiter volume

That's correct and my original question was actually if a two node +
arbiter setup is possible. The documentation provided by Soumya only
mentions two servers in the example ganesha-ha.sh script. Perhaps that
could be updated as well then, to not give the wrong impression.
I could try to change the script to disable quorum, but wouldn't that
defeat the purpose? What will happen in case one node goes down
unexpectedly?
