Yes, fusefs does implement direct_io.

This depends on what gluster does.  Early FUSE protocol levels didn't provide
any primitives for keeping the cache coherent.  Later ones do.  You may be able
to tell which protocol level glusterfs is using if the daemon has some kind of
--verbose option.

> Sorry I'm a bit confused now, doest the BSD implementation of FUSE honour the gluster options?

What options?
