The DC OCF scripts were not updated over the switch to Debian
in StarlingX 8.0. As a result, it could lead to orphan processes
over the service restart or controller swact. The orphan processes
consume resources and perform duplicate/obsolete tasks (e.g.
auditing the same subclouds as the corresponding worker processes)
until their work queues are empty.
This commit fixes up the pgrep option to restore the functionality
of the confirm_stop function of the OCF script. Processes that
fail to be terminated will get killed.
Test Plan:
- Deploy a small DC system. Verify that all DC services can
be started, stopped and restarted by SM.
- Deploy a large DC system with many subclouds. Reduce the
thread_pool_size of dcmanager-audit-worker. Let the system
soak for a couple of hours. Restart the service in the
middle of the audit cycle. Verify that dcmanager-audit-worker
sevice was successfully restarted and there are no orphan
processes.
