Hi all,

Running glusterfs-3.4.2-1.el6.x86_6 on centos6.5

Due to some smart people screw up my network connection on the nodes for don't know how long. I found that I have my GlusterFS volume in split-brain.  I googled and found different way to clean this.  I need some extra help on this.

# gluster volume heal kvm1 info split-brain

1. what's the best way?  

2.gluster volume heal doesnt' really save this, right?

3. kind of shooting from the dark as I can't see the data content. The volume is holding VM images.  Picking the latest copies should be good?
