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.
It does work with 2-node as well. In the script, there is already a
check to verify if the number of servers < 3, it automatically disables
quorum.
Quorum cannot be enabled for a 2-node setup for obvious reasons. If one
node fails, other node just takes over the IP.
Thanks,
Soumya
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?

Hi,
IIRC, the setup is two nodes gluster+ganesha nodes plus the arbiter
node for gluster quorum.
Have I remembered that correctly?
The Ganesha HA in 3.7 requires a minimum of three servers running
ganesha and pacemaker. Two might work if you change the
ganesha-ha.sh to not enable pacemaker quorum, but I haven't tried
that myself. I'll try and find time in the next couple of days to
update the documentation or write a blog post.
