Sadly, split brain is still a bit of a sore spot. It probably will be as long as GlusterFS continues to use the "fan out" replication approach, though past and future enhancements around quorum should help too. On the other hand, it's great to get such positive feedback about the "everything is regular files" doctrine. It has certainly been a bit painful sometimes, especially in terms of performance, but the feeling has always been that the ops advantages are worth it. Nice to see someone else agrees.
(Disclaimer: I'm a GlusterFS developer)
Having the 'bricks' use the regular filesystems was a very smart decision, it means you don't end up in binary hell when things go south.
Split brain was one of the weaker points back in the days, I am not current with the software so no idea if and how much this has improved, someone with more recent experience would be a better guide there.
