Hi , [issue]: To ensure the glusterFS mount point work, a script will periodically using HTTP put a file to subdirectory under
mount point which is used as Apache DocumentRoot. But after running some time, some errors show below: [2015-01-14 09:18:40.915639] E [afr-self-heal-common.c:2868:afr_log_self_heal_completion_status] 0-gv0-replicate-0: metadata self heal failed, on /mpdis [2015-01-14 09:18:41.924584] E [afr-self-heal-common.c:233:afr_sh_print_split_brain_log] 0-gv0-replicate-0: Unable to self-heal contents of '/' (possible split-brain).
