you can control max_backfills and some others if you  set osd_mclock_override_recovery_settings to true On 4/28/26 10:57, Janne Johansson via ceph-users wrote:

Another approach is to set the flags, destroy the OSDs on a single host, redeploy them, set your backfill/recovery throttles down to 1, and unset the flags. This is harder with mclock right? With wpq you can still control max_backfills, but not with mclock unless I am mistaken.
