I am currently working on mysqlfs which is a fuse fs which can be used
in conjunction with mysql-ndb cluster.
You can find the details here: http://sourceforge.net/projects/mysqlfs/
and a howto (in german, though) here:
http://www.netz-guru.de/2008/04/03/mysqlfs-mit-mysql-ndb-cluster-als-verteiltes-dateisystem/
It is working quite well, but still lacks of caching which makes it slow
if your connection between the DB-servers have high latency/many hops.
I don't know BTRFS nor CRFS or POHMELFS but i will take a look at them.
Hope you'll find that usefull.
