Hi ling, The feature for speeding up rebalance by allowing multiple servers to support parallel rebalance is in release 3.3.0. A single rebalance processes is started on every node/server where the volume's bricks exist. These rebalance processes share load between themselves to migrate data, hence reducing the bottleneck of having only 1 rebalance thread do the work. Additionally, all rebalance processes push data to the destination node, hence better utilizing the network too. Hope this answers your query.

Is these a way to speed up rebalancing now in 3.3.0? Is it possible to let rebalancing between multiple servers making use of more of available network bandwidth? I have 5 servers with 10Gb network, and 40Gb infiniband. The copying is going on the 10Gb interface only when I started rebalance, and it's consuming less than 1Gb/s for each streams.
