Hi All, Is it possible at this point in time to setup some form of tiering of storage pools in ceph by modifying the crush map? For example I want to have my most recently used data on a small set of nodes that have SSD's and over time migrate data from the SSD's to some bulk spinning disk using a LRU policy?
