[Libfix] Fix get_brick_processes_count() to use pgrep
Problem: On latest platforms pidof command is returning multiple pids as shown below: 27190 27078 26854 This is becasue it was returning glusterd,glusterfsd and glusterfs processes as well. The problem is that /usr/sbin/glusterd is a link to glusterfsd. 'pidof' has a new feature that pidof searches for the pattern in /proc/PID/cmdline, /proc/PID/stat and finally /proc/PID/exe. Hence pidof matches realpath of /proc/<pid_of_glusterd>/exe as /usr/sbin/glusterfsd and results in glusterd, glusterfs and glusterfsd pids being returned in output. Fix: Use pgrep instead of pidof to get glusterfsd pids. And change the split logic accordingly. Change-Id: Ie215734387989f2d8cb19e4b4f7cddc73d2a5608 Signed-off-by: kshithijiyer <>
