In a Pacemaker cluster, failed actions can occur when a resource fails to start, stop, or perform any other action. To clear failed actions in a CRM cluster, you can use the following command:
crm resource cleanup
This command will clear all failed actions from the cluster. If you want to clear failed actions for a specific resource, you can use the following command:
crm resource cleanup <resource_name>
This command will clear all failed actions for the specified resource.
Another option is to use.
crm_resource --clear-failcount -r <resource>This command will reset the failcount of the failed resource, which is used by Pacemaker to determine when to stop trying to start a resource and mark it as failed.
It’s important to note that clearing failed actions can cause the cluster to try to start or stop a resource again, which can lead to further failures. You should therefore only clear failed actions after you have resolved the underlying issue that caused the failure.
