Description

$ ./bin/ceph fs subvolumegroup create a csi
Error EINVAL: Traceback (most recent call last):

cephfs.Error: (13, "error in mkdir 'b'volumes'': error code 13")

Solution: Inside the ceph-mgr's volumes module, have the filesystem client have uid/gid as 0/0 by using `conf_set` interface, before mounting the ceph filesystem and creating directories.
