Ceph » mgr

After cluster migration from Jevel 10.2.9-0ubuntu0.16.04.1 to Luminous 12.2.2-1xenial on an Ubuntu.16.04.3 LTS (amd64)

ceph df --detail produces no list of pools, although "ceph osd pool ls" provides accurate list of pools.

The problem is not observed when deploying same packages/system configuration with a blank cluster (offline, debian-based deployment using an up-to-date 16.04 apt mirror with luminous .debs)
