          Hello,
          

          We managed to collect

          Brick
              oamhost:/opt/lvmdir/c2/brick/
          Number of entries in

          Brick

          Number of entries in
              split-brain: 0
          

    Why is the same hostname:brick being listed twice? Could you list
    the output of `gluster volume info c_glusterfs` ?

    
          # 
          # 
          # Brick1> gluster
              volume heal c_glusterfs info            
          Brick
              oamhost:/opt/lvmdir/c2/brick/
          /logfiles/security/EVENT_LOG.xml 
          Number of entries: 1
          

          Brick
              oamhost:/opt/lvmdir/c2/brick/
          Number of entries: 0
          

          We couldn't collect
              getfattr output on parent directory.
          We will try to
              reproduce the problem again and provide you the logs.
          

        Thanks, a reproducer +logs would really be helpful.

        
          Meanwhile, can you
              please check and let us know 
          why "gluster volume
              heal c_glusterfs info split-brain" is showing number of
              entries in split-brain as zero?
        
      
        Because the gfid-string of the parent directory seems to be
        missing from the <brick>/.glusterfs/indices/xattrop of the
        bricks.

                    From the extended attributes, an
                        entry split-brain seems to be appeared. Since
                        gfid is different for the original file and its
                        replica.
                    Can you please let us know why
                        the split-brain files are not shown in "gluster
                        volume heal <vol> info split-brain"
                        command? 

                      
                 For gfid mismatches, 'info split-brain` should
                indicate that the parent directory of that file is in
                split-brain. Strange that it isn't.

                If you still have the setup, can you provide the
                getfattr output of the parent dir on both bricks? Also,
                does `gluster vol heal <vol> info ` list the file
                or the parent dir?

                  
                    Kindly let us know if any known
                        issue exists.
