*My Questions*
- is heal and rebalance necessary in order to upgrade replica 2 to
replica 3 ?
No, `gluster volume add-brick voname replica 3
node3.san:/tank/gluster/brick1' should automatically trigger healing in
gluster 3.12 (actually earlier than 3.12 but I don't remember which
release the automatic healing was added on add-brick command). Ensure
that `gluster volume heal volname info` eventually becomes zero.
- is this upgrade procedure OK ? What more/else should I do in order
to do this upgrade correctly ?
Looks okay in theory (I haven't tried out a 3.7 to 3.12 upgrade). It
might be good to check there are no pending heals before you stop the
old nodes for the upgrade.
