When we are doing cache tiering, we are more sensitive to short PG logs because the dup op entries are not perfectly promoted from the base to the cache. See: http://tracker.ceph.com/issues/38358 http://tracker.ceph.com/issues/24320 This works around the problem by not testing short pg logs in combination with cache tiering. This works because the short_pg_log.yaml fragment sets the short log in the [global] section but the cache workloads overload it (back to a large/default value) in the [osd] section.
