Would that be nodes as in different systems? In that case you should
check glusterfs and provide a raincloud module for it.

On the other hand if nodes is just local disks glusterfs might still
be a good way to implement and test your algorithm before putting it
into the kernel.

PS: Isn't the Reed Solomon for x+1 disks == XOR and x+2 disks p+q
parity? I.e. raid4/5/6 are Reed Solomon are just the first 2 cases for
Reed Solomon.
