We have written this simple Linux filesystem which allows the aggregation
of multiple disk volumes. All of the block i/o operations are carried
out with very little extra overhead.
This is still in development, but we have deployed this on our cluster
to build a single 20 Tbyte filesystem (constructed from 16 1.25 Tbyte RAID
volumes).
If anyone else wants to try this, the current version may be found
at: http://hepwww.ph.qmul.ac.uk/~ajm/poolfs/
