# ceph health detail | grep 'ops are blocked'
# ceph osd blocked-by

My guess is that you have an OSD that is in a funky state blocking the
requests and the peering.  Let me know what the output of those commands
are.

Also what are the replica sizes of your 2 pools?  It shows that only 1 OSD
was last active for the 2 inactive PGs.  Not sure yet if that is anything
of concern, but didn't want to ignore it.
