It has never been clear to me how well you can fail over a NFS mount 
using a floating IP address, especially with the Gluster NFS server. I 
typically install gluster on the client and have it mount 
localhost:/whatever and all the brick routing is handles locally. Not 
practical with a lot of clients, but it's a simpler configuration in a 
smaller environment.

If it makes you feel better, I'm in the process of restoring a 
production SVN repo because Gluster 3.2.5 ate it after a node reboot 
last night. Not had time to dig through the logs in detail, but it seems 
like a self-heal from a 4-way replica did something wrong.
