It could be an issue with the devicehealthpool as you are
correct, it is a single PG - but when the cluster is reporting
that everything is healthy, it's difficult where to go from there.
What I don't understand is why its refusing to upgrade ANY of the
osd daemons; I have 33 of them, why would a single PG going
offline be a problem for all of them?
I did try stopping the upgrade and restarting it, but it just picks up at the same place (11/56 daemons upgraded) and immediately reports the same issue.
Is there any way to at least tell which PG is the problematic
one?

Yes I know you are right, eventually we'll switch to an odd number of mons rather than even. We're still in 'testing' mode right now and only my coworkers and I are using the cluster. Of the 7 pools, all but 2 are replica x3. The last two are EC 2+2.
