All the problem pg's are on osd.39. When I stop osd.39, it shows 86
pg's would be offline. However, there is no recovery that happens. It
just stays there. 86 undersized+remapped+peered
I managed to pin down all the pg groups that are in this state by using:
ceph pg dump | grep active+clean+remapped
From there I queried the first pg on the list:
NodeC:~# ceph pg 28.42 query

Can anyone see from this what the reason may be that this (and the other
pg's) are stuck on this osd?

How do I determine the primary osd?
ceph pg map $pg
ceph pg $pg query | jq .info.stats.acting_primary
You can jq and less to take a look at other values which might be
informative too.
Ah, of course :-) Sorry, I was looking for the primary osd of a pool!
No wonder I couldn't find anything. LOL!
