What does Stonith Deathmatch mean?

Preventing a Stonith Deathmatch: The Role of the Collax Fencing Device

If the interconnect fails, both nodes attempt to shut down their respective partners. If both nodes succeed in doing this and take full control without being able to communicate with each other, this is called a “stonith deathmatch”.

The Collax Fencing Device is specifically designed to ensure that a second command to shut down cannot be sent.

To reliably prevent both a split-brain situation and a deathmatch, the Collax Fencing Device has an independent communication channel that is not affected by the interconnect failure. In addition, the Collax Fencing Devices are designed to power each other even if one node fails to maintain communication.
