Something else to help debugging is ceph pg 17.173 query at the end it should say why the pg is incomplete. -- dan On Thu, Aug 20, 2020 at 10:01 AM Eugen Block <eblock@nde.ag> wrote:
Hi Martin,
have you seen this blog post [1]? It describes how to recover from inactive and incomplete PGs (on a size 1 pool). I haven't tried any of that but it could be worth a try. Apparently it only would work if the affected PGs have 0 objects but that seems to be the case, right?
Regards, Eugen

After doing some research I suspect the problem is that during the cluster was backfilling an OSD was removed.
Now the PGs which are inactive and incomplete have all the same (removed OSD) in the "down_osds_we_would_probe" output and the peering is blocked by "peering_blocked_by_history_les_bound". We tried to set the "osd_find_best_info_ignore_history_les = true" but with no success the OSDs keep in a peering loop.

Hi Peter,
On the weekend another host was down due to power problems, which was restarted. Therefore these outputs also include some "Degraded data redundancy" messages. And one OSD crashed due to a disk error.

No it's not a EC pool which has the inactive+incomplete PGs.
ceph osd crush dump | jq '[.rules, .tunables]':
Best, Martin

Dear Martin,
Can you provide some details?
ceph -s ceph health detail ceph osd tree ceph osd pool ls detail
If it's EC (you implied it's not) also show the crush
rules...and may as well include tunables (because greatly raising choose_total_tries, eg. 200 may be the solution to your problem):
ceph osd crush dump | jq '[.rules, .tunables]'
