[Gluster-users] Out of space, rebalance and possibly split-brain issues

[Kaushal M]

Rebalance in gluster-3.2 isn't distributed. The rebalance process is
started only on the peer where the rebalance start command was run.
This is unlike, gluster-3.3 and above where rebalance is distributed
and a rebalance process is started on all peers having bricks of a
volume.
