[root@management-b ~]# rados -p rbd ls rbd_directory [root@management-b ~]# rados -p rbd_cache ls rbd_directory [root@management-b ~]# rados -p rbd lssnap 0 snaps [root@management-b ~]# rados -p rbd_cache lssnap 0 snaps Best regards, On Tue, Jun 14, 2016 at 4:55 AM, Lazuardi Nasution <mrxlazuar...@gmail.com> wrote: > Hi, > > I have removed cache tiering due to "missing hit_sets" warning.
