Well it would not be RAID 5, but you would get redundancy and 2/3rd the space. Take each server and make 2 partitions out of the free space such as: Server 1 Brick 1 Mirror 3 Server 2 Brick 2 Mirror 1 Server 3 Brick 3 Mirror 2 volume block0 type cluster/replicate subvolumes brick1 mirror1 end-volume volume block1 type cluster/replicate subvolumes brick mirror1 end-volume volume block2 type cluster/replicate subvolumes brick2 mirror2 end-volume volume unify type cluster/distribute subvolumes block0 block1 block2 end-volume
