Hi Vivien, Unless you ran 'ceph pg stat' command when peering was occuring, the 37 peering PGs might indicate a temporary peering issue with one or more OSDs. If that's the case then restarting associated OSDs could help with the peering or ceph pg. You could list those PGs and associated OSDs with 'ceph pg ls peering' and trigger peering by either restarting one common OSD or by using 'ceph pg repeer <pg_id>'.
Regarding the unfound object and its associated backfill_unfound PG, you could identify this PG with 'ceph pg ls backfill_unfound' and investigate this PG with 'ceph pg <pg_id> query'. Depending on the output, you could try running a 'ceph pg repair <pg_id>'. Could you confirm that this PG is not part of a size=2 pool?
