In this case, the answer is yes, one could mount a file system, and create separate bricks which belong to different gluster volumes. -- Dave Warren http://www.hireahit.com/ http://ca.linkedin.com/in/davejwarren
You could perhaps use LVM on your RAID 6, and create two Logical Volumes, one per brick?
