The increased concurrency improves performance a lot. But yes, we are on the edge. OMAP+META is almost 50%. Please be careful with that. In the past, I had to help a customer who ran out of disk space on small SSD partitions. This has happened because MONs keep a history of all OSD and PG maps until at least the clean state. So, during a prolonged semi-outage (when the cluster is not healthy) they will slowly creep and accumulate and eat disk space - and the problematic part is that this creepage is replicated to OSDs. -- Alexander E.
