Hi gouthampravi,

Thanks for your reply. I have recheck the issue[1][2] and I found some commands. I run commands as followed:

- docker exec -it -uroot manila_share bash

- mount -t ceph 172.20.0.33:6789:/ /mnt -o name=manila,secret=<manila client key>

- chown 42429:42429 /mnt/

- umount /mnt/

At last, it resolved my issue.

Manila interacts with ceph using a ceph client user (this user is called “manila”by default, but is customizable with config option [1]). It’s likely that user doesn’t have permission to use the data pool that’s assigned to the underlying cephfs file system; can you check these permissions? (called “caps”)

In Train, these are the permissions the ceph client user needs:
https://docs.openstack.org/manila/train/admin/cephfs_driver.html#authorizing-the-driver-to-communicate-with-ceph

Can you check that these permissions match in your deployment?

If they do, check the file permissions for the ceph keyring associated with the user.
