Thanks Luis,
I was hoping I could do dist-upgrade one node at a time. my cluster is very small, only 18 osds between the two osd servers and three mons
I guess it should be safe to shutdown ceph on one of the osd servers, do the upgrade, reboot, wait for PGs to become active+clean and follow the procedure on the second osd server.
Do you think this could work?
Performance wise, i do not have a great IO demand, in particular over a weekend.
Thanks
Andrei

There are several routes you can follow for this work. The best one
will depend on cluster size, current data, pool definition (size),
performance expectations, etc.
They range from doing dist-upgrade a node at a time, to
remove-upgrade-then-add nodes to the cluster. But knowing that ceph is
"self-healing" if you aren't somewhat careful you can do an upgrade
online without much disruption if any (performance will always be
impacted).
