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.
