Fraunhofer FS ? Interesting...

Not that I am aware of.

Ping pong is a good (and usually necessary) start.
Be sure to also run the "ping_pong -rw" test.

Well, in order to run samba+ctdb on any cluster file system,
you should check if samba with out ctdb can serve files
from a single node with that file system (on an exclusively
available file area), to check that the file system is
POSIX enough to be able to be used by samba.
