If your cluster has not used CephFS since before the Jewel release, some legacy data structures may still be in the Ceph Monitor stores. In Pacific and Quincy, the monitors no longer understand how to decode these structures. To avoid this issue [1], please make a short upgrade stop at the just-released Octopus v15.2.14 before continuing on to Pacific/Quincy. After a day's time, the Monitors will have cleared out the old structures.
