Description of problem:
Even after enabling Journal, i am seeing the Mirroring state as Disabled and the image is not getting synced to Slave Node.

Version-Release number of selected component (if applicable):
ceph version 10.2.2-1.el7cp
rbd-mirror-10.2.2-1.el7cp.x86_64

How reproducible:
Once

Steps to Reproduce:
While Reproducing BZ 1347174, same steps as the mentioned BUG

On one of my Image test2, mirroring state is showing as disabled.
Even after enabling the Journaling on the Image, its unable to sync with the Slave Node. Although Journaling feature is showing as enabled but the functionality is not working.

Master:
rbd image 'test2':
        size 10240 MB in 2560 objects
        order 22 (4096 kB objects)
        block_name_prefix: rbd_data.1111238e1f29
        format: 2
        features: layering, exclusive-lock, object-map, fast-diff, deep-flatten, journaling
        flags: 
        journal: 1111238e1f29
        mirroring state: disabled

Slave:
rbd: error opening image test22016-06-16 09:09:42.499601 7ff16cff9700 10 librbd::image::OpenRequest: handle_close_image: r=0
: (2) No such file or directory

Actual results:
Although Journal is showing enabled, but its not working as per expected. Its not syncing to Slave Node.

Expected results:
Journaling should get enabled and the image should sync.
