        Ahh, thank you, now I get it. I deleted it on one node and
          it replicated to another one. Now I get the following output:

          
          [root@gluster1 var]# gluster volume heal gv01 info

          Brick gluster1:/home/gluster/gv01/

          <gfid:d3def9e1-c6d0-4b7d-a322-b5019305182e>

          Number of entries: 1

          
          Brick gluster2:/home/gluster/gv01/

          Number of entries: 0

          
        Is it normal? Why the number of entries isn't reset to 0?

        
    If you access the file using ls/stat etc, it will be fixed. But
    before that could you please post the output of 'getfattr -d -m. -e
    hex file/path/in/backend/brick' and 'getfattr -d -m. -e hex
    parent/dir/to/file/path/in/backend/brick'

        And why wouldn't the file show up in split-brain before, anyway?

      
    Gfid split-brains are not shown in heal-info-split-brain yet.

                      Hello.

                        
                      I've Gluster 3.5.2 on Centos 6. A primitive
                      replicated volume, as describe here. I tried to simulate
                      split-brain by temporarily disconnecting the nodes
                      and creating a file with the same name and
                      different contents. That worked.

                      
                    The question is, how do I fix it now? All the
                      tutorials suggest deleting the file from one of
                      the nodes. I can't do that, it reports
                      "Input/output error". The file won't even show up
                      in "gluster volume heal gv00 info split-brain".
                      That shows 0 entries.

                    
               The deletion needs to happen on one of the bricks,
              not from the mount point.

                    I can see the file in "gluster volume heal gv00
                      info heal-failed", though.
