Hi,
        I have a disperse gluster volume  with 6 servers. 262TB of usable capacity.  Gluster version is 3.7.19.
        glusterfs1, glusterf2 and glusterfs3 nodes were initially used for creating the volume. Nodes glusterf4, glusterfs5 and glusterfs6 were later added to the volume.

        Directory creation failed on a directory called /ws/glus/Folder_07.11.2016_23.02/CV_MAGNETIC.
        # file: ws/glus/Folder_07.11.2016_23.02/CV_MAGNETIC
        glusterfs.gfid.string="e8e51015-616f-4f04-b9d2-92f46eb5cfc7"

        gluster mount log contains lot of following errors:
        [2017-03-09 15:32:36.773937] W [MSGID: 122056] [ec-combine.c:875:ec_combine_check] 0-StoragePool-disperse-7: Mismatching xdata in answers of 'LOOKUP' for e8e51015-616f-4f04-b9d2-92f46eb5cfc7

        The directory seems to be out of sync between nodes glusterfs1, glusterfs2 and glusterfs3. Each has different version.

         trusted.ec.version=0x00000000000839f00000000000083a4d
         trusted.ec.version=0x0000000000082ea40000000000083a4b
         trusted.ec.version=0x0000000000083a760000000000083a7b

         Self-heal does not seem to be healing this directory.

Thanks and Regards,
Ram
