  • How to Update a Red Hat Enterprise Linux Cluster While Minimizing Downtime Authors: Adam Drew and Eva Schaller Editor: Allison Pranger 11/25/2010
    How to Update a Red Hat Enterprise Linux Cluster while Minimizing Downtime Authors: Adam Drew and Eva Schaller Editor: Allison Pranger 11/25/2010 OVERVIEW A rolling upgrade is the process of taking a running cluster and updating packages either from one minor version of Red Hat Enterprise Linux to another (for example, updating a Red Hat Enterprise Linux 5.4 cluster to Red Hat Enterprise Linux 5.5) or updating to the latest errata packages in the same minor release (for example, updating a Red Hat Enterprise Linux 5.5 cluster with the latest Red Hat Enterprise Linux 5.5.z release). NOTE: Rolling upgrades between minor releases of Red Hat Enterprise Linux are fully supported, but rolling upgrades between major releases of Red Hat Enterprise Linux are not supported at this time. This document describes how to perform a rolling upgrade to update software on every node of a cluster while minimizing downtime. Environment • Red Hat Cluster Suite • Red Hat Enterprise Linux 5+ Advanced Platform (Clustering and GFS/GFS2) RECOMMENDATIONS During the upgrade process, the cluster will be running some nodes at one software revision level and other nodes at a higher software revision. It is best practice to minimize the amount of time that the cluster is running with a heterogeneous software configuration. There is no set time limit for how long a cluster may run in this mode, but returning all nodes to the same software versions as quickly as possible is recommended. The specific process you should follow depends on how many nodes are in your cluster and how many versions you are moving between.
