Executing gluster volume set operations on volumes from gluster CLI caused a significant memory leak in glusterd process. The memory leak issues have been fixed in this release.
Created 300 Dist Rep volumes.
Set volume options in loop .
EXACT COMMANDS : for i in {1..300};do gluster v set butcher$i cluster.self-heal-daemon off;sleep 3 ;gluster v set butcher$i group metadata-cache;sleep 3;gluster v set butcher$i cluster.lookup-optimize on;sleep 3 ;done
** BEFORE VOL SET COMMANDS **
[root@gqas013 ~]# ps aux|grep /sbin/glusterd
root 17167 1.1 0.2 600724 109656 ? Ssl 09:01 1:22 /usr/sbin/glusterd -p /var/run/glusterd.pid --log-level INFO
[root@gqas013 ~]#
** AFTER 300*3 VOL SET COMMANDS **:
[root@gqas013 ~]# ps aux|grep sbin/glusterd
root 17167 4.7 0.3 797332 118236 ? Ssl 09:01 38:37 /usr/sbin/glusterd -p /var/run/glusterd.pid --log-level INFO
Memory consumption increased from 109 MB with a small delta, 118 MB.
The same test was tried thrice.
Mem consumption of glusterd seemed controlled.
I am moving this bug to Verified.
