In glusterfs 3.6.2, you can gather required information from heal info, or restarting self-heal daemon should also give you updated split-brain list. # gluster --version glusterfs 3.6.2 built on Apr 22 2015 02:02:49 Repository revision: git://git.gluster.com/glusterfs.git Copyright (c) 2006-2011 Gluster Inc. http://www.gluster.com GlusterFS comes with ABSOLUTELY NO WARRANTY.
