Hi Drew,

Gluster Platform 3.0.X doesn't have straight forward way for volume expansion. 
Its required to do manual change in files,

1. /GLUSTER/volumes.xml on all servers and /GLUSTER/global-volumes.xml file in 
2. Creating volume exports directory under data partition mount 
points(/exports/DISKPARTITION/) in new servers.
3. Editing /etc/glusterfs/*VOLUME*.vol files in all servers and have same copy 
in new servers.

All the above steps should be done when the volume is offline.
