Dear Ceph users yesterday I added a new host to my cluster. This triggered a rebalance and now backfill is in progress. What I'm seeing is that many PGs are in backfill_wait state, and just a few are actually backfilling: pgs: 35081735/215211118 objects misplaced (16.301%) 348 active+remapped+backfill_wait 174 active+clean 7 active+remapped+backfilling I prioritized the recovery by setting the high_recovery_ops scheduler profile, but this just increased the recovery rate a bit while not incrementing the number of actually backfilling PGs. Is there a way to increment the number of PGs that backfill at the same time? I guess this should speed up the operations, but I didn't find a way to do so. Currently I have very little load from users so I can devote all the resources to the recovery. Using Ceph 19.2.0 managed by cephadm. Thanks, Nicola
