If this message is output, check whether a cgroup other than the root cgroup exists in the CPU subsystem (CPU resource controller).#
- #:
-
Other than being created manually, a cgroup in the CPU subsystem other than the root cgroup is created automatically in situations such as the following:
- When a Docker container is started.
- When a service that uses a value specified for CPUShares in the Unit settings file is started.
If a cgroup other than the root cgroup exists in the CPU subsystem, overwrite the value specified for ExecStart in the /usr/lib/systemd/system/HAmon-powercontrol.service file as follows. Overwriting the value causes the HA Monitor process to operate by using the root cgroup explicitly.
-
Before overwriting the value:
: ExecStart=/bin/sh -c '/opt/hitachi/HAmon/bin/HApwon >/dev/null 2>&1' :
-
After overwriting the value:
: ExecStart=/bin/cgexec -g cpu:./ --sticky /bin/sh -c '/opt/hitachi/HAmon/bin/HApwon >/dev/null 2>&1' :
