.Directories configured for Ceph File System mirroring can now be listed using the ceph fs command
Previously, to list the directories configured for mirroring, users had to go through the peer list.
With this enhancement, users can now list the directories configured for mirroring using the ceph fs snapshot mirror ls FS_NAME command. This provides a direct list of the directories configured for mirroring.
Description of problem:
------------------------
We have "ceph fs snapshot mirror add" and "ceph fs snapshot remove" commands to create and remove the paths configured for mirroring.
It would be good if we could also list the paths that are configured for snapshot mirroring. ex: ceph fs snapshot mirror ls <fs_name>".
At present, the path configured can only be seen using the mirror daemon asok file -
