It seems to number downwards from /dev/md127 - if I create md array on the same system it is /dev/md126. However, this does suggest that the nodes are not configured identically: two are /dev/sda or /dev/sdb, which suggests either plain disk or hardware RAID, while two are /dev/md0 or /dev/127, which is software RAID. Although this could explain performance differences between the nodes, this is transparent to gluster and doesn't explain why the files are unevenly balanced - unless there is one huge file which happens to have been allocated to this node.
