[2015-03-11 11:18:31.957505] E [afr-self-heal-common.c:233:afr_sh_print_split_brain_log] 0-md1-replicate-2: Unable to self-heal contents of '/library' (possible split-brain). Please delete the file from all but the preferred subvolume.- Pending matrix:  [ [ 0 2 ] [ 1 0 ] ]
[2015-03-11 11:18:31.957692] E [afr-self-heal-common.c:2868:afr_log_self_heal_completion_status] 0-md1-replicate-2:  metadata self heal  failed,   on /library
