Hi,
The Ceph cluster is with Pacific v16.2.10.
"rbd mirror image enable <image> journal" seems not working.
Any clues what I'm missing? There is no error messages from the CLI.
Any way to troubleshooting?
```

In case the image has parent, the parent image also needs to be mirrored.
After enabling the mirroring on parent image, it works as expected.
Thanks!
