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 :) -- Lindsay Mathieson
