Comment 16 for bug 1806156

Looking at it a bit more yields the following:
1. It can't handle rbd:
2. The volumes in ceph has shared_targets set
3. it's "capabilities = rpcapi.get_capabilities(" on line 111 that fails to get information somehow...

A quick hack gets information about the storage backendv3 just fine.

It looks like this should have
if service.host[:4] == "rbd:":
    next
