If someone has experience to share in this area, i'd be grateful.  I have an existing distributed replicated volume, 2x16.

We have a third server ready to go.  Redhat docs say just run add brick replica 3, then run rebalance.

The rebalance step feels a bit off to me.  Isn't some kind of heal operation in order rather than rebalance?

No additional usable space will be introduced, only replica count increase from 2 to 3.

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.
