In my setup I've disabled the sharding and preshard each bucket which needs 
more then 1.1 millions of objects.
I don't think it's possible to cleanup, even if you run the command with the 
really-really mean it, it will not do anything, I've tried already.

So you did setup a sync policy to only sync in one direction?

In my setup the secondary site does not receive any writes anyways, so it's 
likely not about changes that happend to the same bucket in both sites.
Somehow I ended up with a few stale instances in both sites though - but some 
even for buckets which don't exist anymore and the lists are not the same. The 
lists don't appear to be growing, but still, I'd like to clean those up.

I did not explicitly disable dynamic sharding in ceph.conf until recently - but 
question is, if this was even necessary since RGW does recognize when it's 
running in multisite sync.
