Sounds like you're building a LittleFe! (http://LittleFe.net/) (Maybe
not, but a similar setup.)

I'm pseudo involved in this part of a project right now on
aforementioned LittleFe, but I don't know those details. You may look
towards UnionFS, and these now out-of-date pages may be of some use to
you: https://wiki.cs.earlham.edu/index.php/BCCD . You also may have
more luck on the Beowulf mailing lists (http://beowulf.org/).
