You don't need to run re-balance for increasing the replica count. Heals
should automatically be triggered when you run 'gluster vol add-brick
<volname> replica 3 <list of bricks for the 3rd replica>`. It is
advisable to do this when there is no I/O happening on the volume. You
can verify that files are getting populated in the newly added bricks
post running the command.
