Dealing with Cluster Failures

Assess the Situation

This topic is designed to help resolve common failure scenarios that one may encounter during cluster operation.

The most important step in resolving any cluster failure is to assess your cluster and determine:

• Are there any network issues that are preventing the cluster from operating properly?

• Are there any recent hardware issues?

• Are any of the drives suddenly experiencing issues?

• Is your cluster utilizing high availability, and, if so, which replication mode is it using (redundancy-1 or redundancy-2)?

Knowing the answers to these questions will help you decide which of the following sections will help you resolve your issue(s) and whether any data loss will be incurred.
