vcs basics – Communication faults, jeopardy, split brain, I/O fencing
Let us now see various communication faults that can occur in the VCS cluster and how VCS engine reacts to these fault. There are basically 2 types of communication failures 1. Single LLT link failure (jeopardy) When a node in the cluster has only the last LLT link intact, the node forms a regular membership […]
