Hello everyone,

I was trying a Swift setup having single replica configured with 4 devices added to the ring with different IP addresses.
Later (after all replication/rebalance completed) I uploaded many objects in a multiple containers.
I observe the data movement across these devices through rsync replicator daemon.

I understand that the object rebalance (using rsync) should happen only when we add devices or change weight value in ring (and if multiple replicas configured). 
So what is a reason that it performs data movement (of newly uploaded objects) without any ring changes and single replica?

Thanks in advance,
Tushar
