Sounds similar with how one configures iscsi with pacemaker, where one uses
portblock to ease the transition of clients in the event of migration.

I will run the all setup to make all steps clear in my mind. I was confused
from the following commands which were not recognized (using Debian 10)

gluster nfs-ganesha enable

gluster volume set <volname> ganesha.enable on

I might be missing some step.
