Any other suggestions? There is an alternatives like Ceph[1], but it is 
just too new (and potentially can have some edge cases).

DRBD + GFS/OCFS2 just seem too complex for such setup.

Other than that, I use glusterfs in several setups, and I don't have any 
dramatic performance problems with it (still slower than bare metal of 
course) - will depend on workload and expected performance of course.
