Hi, what exactly is your question? You seem to have made progress in bringing OSDs back up and reducing inactive PGs. What is unexpected to me is that one host failure would cause inactive PGs. Can you share more details about your osd tree and crush rules of the affected inactive PGs? Usually, a ceph cluster should be resilient to a host failure if set up properly. So after your host failed I would have expected that ceph recovers the degraded PGs to different hosts. Did the recovery not happen? Regards, Eugen Zitat von Alfredo Rezinovsky <alfrenovsky@gmail.com>:
I had a problem with a server, hardware completely broken.
"ceph orch rm host" hanged, even with force and offline options
I reinstalled other server with the same IP address and then I removed the OSD with:
ceph osd purge osd.10 ceph osd purge osd.11
Now I have 0.342% pgs not active
with
ceph pg <pg.id> query
I can see the PG is blocked by a non existent OSD.10 or 11 (in the other problematic PG)
I already tried setting
osd_find_best_info_ignore_history_les = false
in the intervening OSDs and restarted them with some luck (I had 3 non active PGs, now I have 2)
Also after that another OSD keeps restarting. Fixed that by setting the reweight to 0 and still waiting until the OSD is empty to destroy it.
