Afaik it involves replace-brick commands (use this on >= 3.3.1).

So instead of the add-brick you'd do something like this :

- replace-brick gluster00:exp0 gluster02:exp0

You go to sleep for 2 days ;-)

- replace-brick gluster01:exp0 gluster02:exp1

You sleep another 2 days, then

- add-brick gluster00:exp0 gluster01:exp0

and then start the 2 rebalance steps.
