Hi,

I created a swift cluster and configured the rings like this...

swift-ring-builder object.builder create 10 3 1

ubuntu-202:/etc/swift$ swift-ring-builder object.builder
object.builder, build version 12
1024 partitions, 3.000000 replicas, 1 regions, 4 zones, 12 devices, 300.00
balance
The minimum number of hours before a partition can be reassigned is 1
Devices:    id  region  zone      ip address  port  replication ip
replication port      name weight partitions balance meta

Container and account rings have a similar configuration.
Once the rings were created and all the disks were added to the rings like
above, I ran rebalance on each ring. (I ran rebalance after adding each of
the node above.)
Then I immediately scp the rings to all other nodes in the cluster.

I now observe that the objects are all going to 10.3.0.202. I don't see the
objects being replicated to the other nodes. So much so that 202 is
approaching 100% disk usage, while other nodes are almost completely empty.
What am I doing wrong? Am I not supposed to run rebalance operation after
addition of each disk/node?

Thanks in advance for the help.
