One section mentions Luminous clusters _with_ EC pools specifically, the other
section mentions Luminous clusters running 12.2.5. 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.

Please clarify,

Thanks,

Stefan
