[ale] distributed network file system

[John Heim]

I would like to set up a distributed network file system in my department. 
There is a dizzying array of possibilities, gfarmfs, ceph, glusterfs, just 
to name a few.

Needs:
1. Should work on a large number of small nodes, 100Gb each.
2. Parallelism & striping.
3. Prefer debian package, GPL.
4. Meta data in mysql would be nice.

Any experience and/or recommendations?
