ceph pg force_create_pg 0.21 We've been playing last week with this same scenario: we stopped on purpose the 3 OSD with the replicas of one PG to find out how it affected to the cluster and we ended up with a stale PG and 400 requests blocked for a long time. After trying several commands to get the cluster back the one that made the difference was force_create_pg and later moving the OSD with blocked requests out of the cluster. Hope that helps, Alex
