From cae9512d60f5715459ea5883c657c679197982d9 Mon Sep 17 00:00:00 2001 From: Gaurav Kumar Garg Date: Tue, 1 Dec 2015 19:14:08 +0530 Subject: glusterd: stop daemon services upon peer detach correctly Problem: Currently glusterd is stopping all the daemons service upon peer detach. If user have multi node cluster and if user want to detach any node from the cluster, and detached node having stand alone volume then upon detaching glusterd stopping all the daemon's of the detached node, which is having running volume. Fix: Upon peer detach it should do peer detach cleanup properly and it should stop only those daemon on the node on which it require.
