Doc Text:	With this update, the CephFS drivers in the OpenStack Shared File Systems service (manila) are updated so that you can manage provisioning and storage lifecycle operations by using the Ceph Manager API. When you create new file shares, the shares are created in a new format that is quicker for creating, deleting and operations. This transition does not affect pre-existing file shares.

Description Goutham Pacha Ravi 2019-10-30 16:23:28 UTC

Description of problem:

The CephFS driver currently uses the Ceph-volume client [1][2]. ceph-mgr [3] is the new supported interface to Ceph recommended by the ceph storage team and currently used by the ceph-csi driver [4].

To implement future features in manila (create share from snapshot, manage-unmanage), it makes sense to rely on the ceph-manager instead of the ceph-volume client. 

From [3], 
"Since the 12.x (luminous) Ceph release, the ceph-mgr daemon is required for normal operations. The ceph-mgr daemon is an optional component in the 11.x (kraken) Ceph release."
