Resilient Storage in RHEL

Steps to install High Availability Resilient Storage cluster packages GFS2 on Red Hat Enterprise Linux

Register your RHEL system and install high-availability packages.

Get the Repo ID details list all the available repositories using the command:
subscription-manager repos --list

Each node in the cluster must have the appropriate subscriptions for RHEL and the High Availability Add-on or Resilient Storage Add-On. The repository should correspond to the RHEL version and optionally the extended support level of the systems. Each node in the cluster must have the appropriate repository enabled with Red Hat Subscription Manager.

Sample repositories for each RHEL version are given below:

RHEL9
rhel-9-for-x86_64-highavailability-rpms

RHEL8
rhel-8-for-x86_64-highavailability-rpms

RHEL 7
rhel-ha-for-rhel-7-server-rpms

RHEL 6
rhel-ha-for-rhel-6-server-rpms

Registering Systems to Install Resilient Storage Packages

The repository should correspond to the RHEL version and the extended support level of the systems. If the cluster will require packages enabling shared storage support, such as for GFS2, lvm2-cluster (clvmd), cmirror, ctdb, etc., then all nodes will also need to have the appropriate repository enabled with Red Hat Subscription Manager. Make sure there is no version mismatch between cluster nodes. Each cluster node must use the same version of cluster-related packages for this to work.

Sample repositories for each RHEL version are given below:

RHEL 9
rhel-9-for-x86_64-resilientstorage-rpms

RHEL 8
rhel-8-for-x86_64-resilientstorage-rpms

RHEL 7
rhel-rs-for-rhel-7-server-rpms

RHEL 6
rhel-rs-for-rhel-6-server-rpms

Installing Packages using Yum

Install the High Availability Clustering packages:
yum groupinstall 'High Availability'
