.The mgr/volumes CLI can now be used to list cephx auth IDs Earlier, `ceph_volume_client` interface was used to list the cephx auth IDs. This interface is now deprecated. With this release, consumers like Manila can use the mgr/volume interface to list the cephx auth IDs that are granted access to the subvolumes. .Syntax ---- ceph fs subvolume authorized_list _VOLUME_NAME_ _SUB_VOLUME_NAME_ [--group_name=_GROUP_NAME_] ----

Description Victoria Martinez de la Cruz 2020-09-16 14:44:46 UTC 
Some cephfs users need the list of auth IDs that have been granted access to a share/subvolume. An example of this is openstack manila, see https://github.com/openstack/manila/blob/stable/train/manila/share/drivers/cephfs/driver.py#L456

The ceph_volume_client's get_authorized_ids() provides this functionality. https://github.com/ceph/ceph/blob/octopus/src/pybind/ceph_volume_client.py#L1308
The ceph_volume_client stores the auth IDs that have been given access to a subvolume in special metadata files, and fetches the list of auth IDs when requested. mgr/volumes needs to provide the same functionality. It needs to store and fetch auth IDs in the same special metadata files used by the ceph_volume_client.

Do we have any update on this? Can we expect the fix to be part of 4.2 ?
