Recovery task

The recovery task defines the recovery attributes of a component. A recovery action is triggered when a component terminates abnormally or when the watchdog heartbeat fails. An abnormal termination is a component termination that wasn't triggered by plms.

Only the statements defined in the Recovery task section are allowed for the recovery task.

Format

task "recovery" {
    repair = "NONE|STOP|RESTART|FAULT|DSS"
    max_tries = retry_value
    wait_time = value_to_wait_between_restarts
}

Default

A default recovery task is defined for every component with default parameters.

Example

task "recovery" {
    max_tries = 5
}

Multiplicity

Zero or one instance in a component block.

Constraints

• The recovery task is a reserved keyword; the parameters shown are the only ones allowed.
• The recovery task is not allowed in a start_sequence or a stop_sequence.
• A recovery action is triggered when a component terminates abnormally. If a component termination is not triggered by PLMS, then the termination of the component is considered as an abnormal termination.
