Ceph is not able to determine the size of a cache pool automatically, so the configuration on the absolute size is required here otherwise the flush/evict will not work. see http://docs.ceph.com/docs/master/rados/operations/cache-tiering/ Change-Id: I4d4abb50787093a292e1ee6eb790c10ecf5ccb94 Closes-Bug: #1654375
