[RHGS] high mem/cpu usage, brick processes not starting while testing CRS scaling with multiplexing
Issue
When testing scaling possibilities of RHGS used as container ready storage with multiplexing, glusterd is failing during provisioning after starting/creating 100-200+ volumes.
Symptoms:
- all gluster commands end on timeout
- inconsistent number of /usr/sbin/glusterfsd processes across the cluster
- glusterd in stale state on some nodes. Running systemctl start/stop/restart has no effect. Only way to stop it is (p)kill -9
Environment
- Red Hat Gluster Storage 3.3.x
