I think it's new in 12.2.10, but it should only show up when using Filestore OSDs. Since you mention that the cluster is new: are you not using Bluestore?
That being said: the default crush rule name is "replicated_rule", so "ceph osd pool create <name> <pg> <pg> replicated_rule <expected_objects>" is the right way to create a pool on a filestore cluster now. I think there's some room for improvement from a user experience point of view... Paul -- Paul Emmerich Looking for help with your Ceph cluster?
