[nycbug-talk] BSD Cluster Filesystem Roundup

On 2/17/2009, DragonFly 2.2 was released[1]. One of the most  
interesting aspects of this release is that HAMMER is now considered  
production ready. If you are not familiar with what HAMMER is, check  
out Matt Dillon's talk from NYCBSDCon 2008 [2] for more information.

I am curious if anyone has played around with HAMMER and would be  
willing to provide us with a trip report? Actually, I would be curious  
to find out what your experience has been with DragonFly as a whole.

Recently, I stumbled upon gluster[3] which is an open source (GPL3)  
clustered filesystem that supports Linux, Mac OS X and FreeBSD 7.
It aggregates various storage bricks over Infiniband RDMA or TCP/IP  
interconnect into one large parallel network file system. It makes
use of FUSE which seems a bit suspect, but they say they can still  
sustain 1 GB/s per storage brick over Infiniband RDMA. To me, this  
looks like the most promising clustered filesystem that supports BSD.

I guess the question becomes, what other clustered filesystems are  
there that support BSD and has anyone deployed them to production?
