eblock, Thanks for your reply. I have read the report [1] but it can not fix my issue.

In our manila-share container, the manila-share service is running by manila
user not root user.

When I run as root user into manila-share container with command like
"docker exec -it -uroot manila_share bash". And then run "python" into
interactive model. Then run code as followed:
import ceph_volume_client
share={"share_group_id":None,"id":"449a52a4-f19c-4d1b-b437-7dc2443e040c"}
c=ceph_volume_client.CephFSVolumeClient("manila", "/etc/ceph/ceph.conf", "ceph", volume_prefix="/volumes")
c.connect(premount_evict="manila")
v=c.create_volume(ceph_volume_client.VolumePath(share['share_group_id'], share['id']), size=1073741824, data_isolated=False, mode=int('755',8))
I can succeed to create the volume.

But when I run as manila user into manila-share container with command
like "docker exec -it manila_share bash". And then run the same python
codes, it will raise the same error which appears in the manila-share.log file.
