Dear all, System: latest Octopus, 8+3 erasure Cephfs
I have a PG that has been driving me crazy. It had gotten to a bad state after heavy backfilling, combined with OSD going down in turn. State is: active+recovery_unfound+undersized+degraded+remapped I have tried repairing it with ceph-objectstore-tool, but no luck so far. Given the time recovery takes this way and since data are under backup, I thought that I would do the "easy" approach instead and: * scan pg_files with cephfs-data-scan * delete data beloging to that pool * recreate PG with "ceph osd force-create-pg" * restore data Although, this has shown not to be so easy after all. ceph osd force-create-pg 20.13f --yes-i-really-mean-it seems to be accepted well enough with "pg 20.13f now creating, ok", but then nothing happens. Issuing the command again just gives a "pg 20.13f already creating" response. If I restart the primary OSD, then the pending force-create-pg disappears. I read that this could be due to crush map issue, but I have checked and that does not seem to be the case. Would it, for instance, be possible to do the force-create-pg manually with something like this?: * set nobackfill and norecovery * delete the pgs shards one by one * unset nobackfill and norecovery Any idea on how to proceed from here is most welcome.
