        Hi,
        

        We have a 2 server replica gluster, about 10TB (5 bricks)
          on each side. The servers are fairly high-end and are
          connected via a private ethernet connection, appearing to
          replicate with each other very quickly.
        

        Running Ubuntu Precise (12.04) and GlusterFS 3.4.1 on the
          servers.
        

        They're working quite heavily in production and downtime is
          difficult to arrange.
        

          We've had a lot of trouble with split-brain, where files/dirs
          on both sides appear identical
        (md5sum, datestamps, etc) but I've fixed most of them by
          erasing the affected files 
        on one side and letting it re-sync.
        

        However, we're left with split brain on '/' and several top
          level directories. 
        I'm uncomfortable erasing that much of one side to solve
          the problem.
        

          any advice?
      
    
    Hope this document helps:

    We are going to provide CLI for these issues in 3.6/3.7 versions
    hopefully.
