You *CAN NOT* safely proceed when a node stops responding _until_ you have put the lost node into a known state. To do otherwise would be to risk a split-brain. A good fence device are switched PDUs, like the APC-brand AP7900 (not all makes/models are supported, so check first before buying other brands). The AP7900 can usually be found used for ~$200 and makes an excellent external fence device. Trying to use DRBD without proper fencing will result in pain and heartache. The delay needed to fence a lost node is FAR preferable to risking a split-brain. -- Digimer Papers and Projects: https://alteeve.ca/w/ What if the cure for cancer is trapped in the mind of a person without access to education?
