Description James Biao 2021-03-29 05:29:26 UTC 
Describe the issue:

When injecting / backup monmap with ceph-mon command under root user, ceph minitor db file permission will be changed to root:root, causes ceph monitor start fail. change ownership of the mon db files back to ceph:ceph can start the monitor again.

Describe the task you were trying to accomplish:

Suggestions for improvement:

change all command line examples to use 'ceph' user to run ceph-mon extract or inject. suggest to include a 'notice' or 'warning' about using ceph user, not root user to run the command
