Forgot to say, this is an octopus 15.2.9 cluster, there isn't any force_create_pg option that has couple of thread to make it work.

Bug #10411: PG stuck incomplete after failed node - Ceph - Ceph<https://tracker.ceph.com/issues/10411>
Yesterday, I was in the process of expanding the number of PGs in one of our pools. While I was doing this, one of the disks in an OSD failed (probably due to the high load of the cluster at that point).

Hi,


What can I do with this pg to make it work?
We lost and don't have the osds  61,122 but we have the 32,33,70. I've exported the pg chunk from them, but they are very small and when I imported back to another osd that osd never started again so I had to remove that chunk (44.1aas2, 44.1aas3) to be able to start the osd.
