glusterd: Gluster should keep PID file in correct location
Currently Gluster keeps process pid information of all the daemons and brick processes in Gluster configuration file directory (ie., /var/lib/glusterd/*). These pid files should be seperate from configuration files. Deletion of the configuration file directory might result into serious problems. Also, /var/run/gluster is the default placeholder directory for pid files. So, with this fix Gluster will keep all process pid information of all processes in /var/run/gluster/* directory.
