With mClock, osd_max_backfills and osd_recovery_max_active can be modified at runtime after setting osd_mclock_override_recovery_settings to true. See the docs <https://docs.ceph.com/en/latest/rados/configuration/mclock-config-ref/#steps-to-modify-mclock-max-backfills-recovery-limits> for more information.
There's no change in the behavior when recovery/backfill limits are modified with mClock enabled. I suspect when you added a new osd, the recovery traffic you observed could just be related to the backfill operation trying to move data due to PGs mapped to the new osd. -Sridhar _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
