Bug description:
There is an issue with swift-ring-builder and rebalancing under
certain conditions beginning in Mitaka.
Steps to reproduce:
Create a ring with part power of 12. 3 servers with 11 devices each, BUT 2 servers in zone 1 and one server in zone 2. After adding all devices as described above, swift-ring-builder <ring>.builder rebalance does not return and seems to run into an endless loop.
The weirdness starts with the 11th device, 10 devices still work. It
does not matter whether you add each 10 devices from the 3 servers and
rebalance, and than add the 11th device from each server afterwards or
do it all at once.
This behaviour does not exists in Liberty and starts with Mitaka.
For connivence I am adding the statements to reproduce:
