I might be misreading this, but to make things clear for current Ceph Luminous 12.2.5 users. Is the following statement correct? If you do _NOT_ use EC in your 12.2.5 cluster (only replicated pools), there is no need to quiesce IO (ceph osd pause). http://docs.ceph.com/docs/master/releases/luminous/#upgrading-from-other-versions If your cluster did not run v12.2.5 or v12.2.6 then none of the above issues apply to you and you should upgrade normally. ^^ Above section would indicate all 12.2.5 luminous clusters.
