I tested by:

- removing brick 3

- erasing brick 3

- closing down all VM's

- adding new brick 3

- waiting until heal number reached its max and started decreasing

   There were no reverse heals

- Started the VM's backup. No real issues there though one showed IO 
errors, presumably due to shards being locked as they were healed.

- VM's started ok, no reverse heals were noted and eventually Brick 3 
was fully healed. The VM's do not appear to be corrupted.


So it would appear the problem is adding a brick while the volume is 
being written to.
