I had a go at reproducing it last night Kevin with 3.8.4

- new volume

- Initial 2 bricks on two hosts

- copied a windows VM on to it

- Started some load (Crystal DiskMark in the VM)

- Added a 3rd brick and node



The 3rd bricks started healing right away and there were no issues. 
Eventually it was all healed and a normal rep 3 volume. Tonight I'lll 
compare the bricks with md5 but for now it seems ok.

- It was only one 40GB VM

- Not sure if the procedure is how it originally started for you.


If you'd like me to try a different process I can give it a goo, have 
the space and time and the cluster has been quite for weeks - time to 
break something :)
