    That version does not have the real-time gfapi based version of the
    `info split-brain` command and it just prints prior event history
    from the selfheal daemon's memory. You can restart selfheal daemon
    to get rid of it.  Or you could ignore the message. Probably a good
    time to upgrade to 3.7 or 3.8.

        Yes, the file gfid file still was present

                  I have a 2 node cluster that reports a
                    single file as split brained .. but the file itself
                    doesn't exist on either node.  
                
               What is the version of gluster you are running?

                
                  I did not find this scenario in the
                    split brain docs, but based on other scenarios I
                    deleted the gfid file
                
               You mean even though the file did not exist, the
              .glusterfs/<gfid-hardlink-to-file> still was
              present?

                   and then ran a full heal, however; it
                    still complains about split brain.   I am
                    considering just restoring the bricks from snapshot,
                    but in the future that may not be ideal.   Is there
                    another way to resolve this?
