A fenced node in an ‘sbd’ setup now shuts down reliably
Previously, when a node received an ‘off’ via the poison pill mechanism used by ‘sbd’ on a shared disk, the node would be likely to reboot instead of powering off. With this fix, receiving an ‘off’ will power off the node. Receiving a ‘reset’ will reboot the node. If the node is not able to perform the software-driven reboot or power off properly, the watchdog is going to trigger and the action performed is what the watchdog device is configured to. A fenced node in an ‘sbd’ setup now shuts down reliably if the watchdog device is configured to power off the node, and fencing is requesting ‘off’ via the poison pill mechanism on a shared disk.
