Hello Joffrey, You could be hitting the slow backfill/recovery issue with mclock_scheduler. To confirm the above could you please provide the output of the following commands? 1. ceph versions 2. ceph config show osd.<id> | grep osd_max_backfills 3. ceph config show osd.<id> | grep osd_recovery_max_active 4. ceph config show osd.<id> | grep osd_mclock where 'id' can be any valid osd id. With the mclock_scheduler enabled and with 17.2.5, it is not possible to override recovery settings like 'osd_max_backfills' and other recovery related config options. -Sridhar _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
