Description Oyvind Albrigtsen 2020-03-23 14:55:02 UTC

Description of problem:
Added a function called get_self_power_status() in which the instance executing the fence action will check its own status before fencing the other node. If the local EC2 instance's status is not "Running" it will not try to fence the other node as the local node has been already fenced. With the addition of this feature pcmk_delay_max and/or pcmk_delay_base can now be used and are encouraged to be used with fence_aws.
