Hello, after rebooting a ceph node and the OSDs starting booting and joining the cluster, we experience slow requests that get resolved immediately after cluster recovers. It is improtant to note that before the node reboot, we set noout flag in order to prevent recovery - so there are only degraded PGs when OSDs shut down- and let the cluster handle the OSDs down/up in the lightest way. Is there any tunable we should consider in order to avoid service degradation for our ceph clients?
