Some additional information. Even though the pgs report unknown, directly querying them seems like they are correctly up.
What could be causing this disconnect in reported pg states?
```
$ ceph pg dump_stuck inactive | head
ok
PG_STAT STATE UP UP_PRIMARY ACTING ACTING_PRIMARY
16.fc unknown [] -1 [] -1
16.fb unknown [] -1 [] -1
16.fa unknown [] -1 [] -1

```
```
$ ceph osd dump | grep epoch
epoch 54661
```
```
$ ceph pg 16.fc query
