FYI, we used this at the company I last worked for. Corrupted our entire filesystem and took down an 8 node production cluster. After weeks of user complaints, downed systems and the like they bought a SAN. I left the company before it was implemented, but I think it's stable now. At some point we let the Gluster developers in to test on the machines (scary, yes) and they were unable to fix the issue.
