>> If so why the client op priority is default 63 and recovery op is 3? This means that by default recovery op is more prioritize than client op! > > Exactly the opposite. Client ops take priority over recovery ops. And various other ops have priorities as described in the document I pointed you to. Now that I poke around, I do find some resources that claim that a *lower* osd_recovery_op_priority value *increases* the priority of recovery ops vs client ops, eg. this one: https://www.suse.com/support/kb/doc/?id=000019693 This is counter to everything I’ve always been told and observed. Poking around in the sources my should-be-in-bed eyes don’t find a definitive answer, but I do see in OpRequest.cc : if (req->get_priority() < tracker->cct->_conf->osd_client_op_priority) { // don't warn as quickly for low priority ops warn_interval_multiplier = tracker->cct->_conf->osd_recovery_op_warn_multiple; } which seems to corroborate the idea that a lower value is a lower priority. If we can get consensus here I’ll add a bit to the docs to make the relationship more clear. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
