In this video, Robert McMillen talks about how to setup a quorum that allows votes to be used to determine which server is in charge of a cluster and can host the cluster roles assigned to it. This ensures that the cluster continues to run properly no matter what event may occur that could bring it down.
- [Voiceover] Quorum is a very important part of clustering…which has to do with high availability.…Setting up quorum allows votes to be used…to determine which server is in charge of a cluster,…and can host the cluster roles assigned to it.…This ensures that the cluster continues to run properly…no matter what event may occur that could bring it down.…So why is configuring quorum important?…Well it has a direct effect on the high availability…of the cluster for the following reasons.…It helps ensure that the fail of our cluster…can start properly or continue running…when the active cluster membership changes.…
Membership changes can occur because of…planned or unplanned node shut-downs,…or when there are disruptions in connectivity…between the nodes or with cluster storage.…When a subset of nodes cannot communicate with each other,…that can be called a split cluster.…The cluster quorum configuration helps ensure that…only one of the subsets continues running as a cluster.…The subsets that do not have enough quorum votes…
