Hi Jeff,

Yes, that's right. On smbd restart it'll reconnect and get a new
instance ID. The hostname is carried in the metadata, which makes it a
little easier to identify what's going on from the Ceph side.
AFAICT the service record (unfortunately) remains present after
rados_shutdown() until a timeout on the manager is tripped, so
it's quite possible to have to registrations for the same host for a
short amount of time.
Cheers, David
