Hello all,
We have a replicated cluster in Nautilus. Recently, we resharded a bucket
without stopping the gateways, as a consequence, the bucket on the
secondary zone now reports 0KB usage, even though you can still see the
objects in the data pool.
I was able to reproduce the issue in a lab, so it's easy to show. i
uploaded around 3000 empty text files :

Is there a way I can fix this situation? make Cluster2 realize he still has
the objects related to ''testbucket'' ? or at least a way where i can re-do
the synchronization from scratch on that bucket? I already tried "data
sync init" and "metadata sync init" but it didn't do the trick.
