I think right now you'll find that you can add an EC pool to the CephFS data pools if it has a cache pool, but doing so will prevent removing the cache pool. -Greg _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
