Can you create a new tracker ticket at [1]? It looks like librbd is
not returning a default "unknown" status for the local site if you
aren't running "rbd-mirror" daemons. The dashboard is a little behind
in supporting all the latest RBD mirroring changes, in this case the
ability to see the global mirroring status from any site (local or
remote).
