[ceph-users] Large number of misplaced PGs but little backfill going on

Hi We have this after adding some hosts and changing crush failure domain to datacenter: pgs: 1338512379/3162732055 objects misplaced (42.321%) 5970 active+remapped+backfill_wait 4853 active+clean 11 active+remapped+backfilling We have 3 datacenters each with 6 hosts and ~400 HDD OSDs with DB/WAL on NVMe. Using mclock with high_recovery_ops profile. What is the bottleneck here? I would have expected a huge number of simultaneous backfills. Backfill reservation logjam? Mvh.
