Abstract
Aspects relate to managing tie-breaking in a multi-node cluster. Methods and systems include detecting, by a first node of the multi-node cluster, that a private network connected to a second node of the multi-node cluster has failed, the first node configured to provide service to a client and access a quorum disk of the multi-node cluster. The first node then communicates with an external point and determines whether the external point is successfully communicated with. The first node determines if a time delay should be imposed, waits for any determined time delay, and attempts to reserve the quorum disk. The first node then verifies it has reserved the quorum disk and obtains operational quorum when the quorum disk is reserved by the first node.
