If CF cannot perform a heartbeat for 10 minutes, it is determined that a heartbeat fails. In the environment where the system is overloaded and a heartbeat failure occurs often, tune the heartbeat time.
Note
If you set the heartbeat time long, it takes long to detect an error. Therefore, tune the heartbeat time carefully.
To tune the heartbeat time (10 seconds), perform the following procedure:
Add the following to the end of the "/etc/default/cluster.config" file on all nodes configuring a cluster system. To restore it, take a note of the contents before changing it.
CLUSTER_TIMEOUT "second"
Example: Changing it to 30 seconds
CLUSTER_TIMEOUT "30"
Restart all nodes configuring a cluster system.
