NOTE: The correct repository name may vary depending upon the subscription that provides the High Availability or Resilient Storage components along with the system architecture.

In order to list all the available repositories, please use the following command. This helps to get the Repo ID details:

# subscription-manager repos --list

Registering Systems to Install High Availability Packages

  • Each node in the cluster must have the appropriate subscriptions for RHEL and the High Availability Add On or Resilient Storage Add On.

  • Each node in the cluster must have the appropriate repository enabled with Red Hat Subscription Manager. The repository should correspond to the RHEL version and optionally the extended support level of the systems.

Following are the example repository names as per the OS version:

RHEL9

Repository: rhel-9-for-x86_64-highavailability-rpms

RHEL8

Repository: rhel-8-for-x86_64-highavailability-rpms

RHEL 7

Repository: rhel-ha-for-rhel-7-server-rpms

RHEL 6

Repository: rhel-ha-for-rhel-6-server-rpms

Registering Systems to Install Resilient Storage Packages

  • Each node in the cluster must have the appropriate subscriptions for RHEL and the Resilient Storage Add On.

  • Optionally, 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. The repository should correspond to the RHEL version and optionally the extended support level of the systems.

Following are the example repository names as per the OS version:

RHEL 9

Repository: rhel-9-for-x86_64-resilientstorage-rpms

RHEL 8

Repository: rhel-8-for-x86_64-resilientstorage-rpms

RHEL 7

Repository: rhel-rs-for-rhel-7-server-rpms

RHEL 6

Repository: rhel-rs-for-rhel-6-server-rpms

Installing Packages Using the Conga Cluster Administration Server in RHEL 6

  • If the RHEL 6 cluster in question will be configured and administered by Conga, an option is provided to install packages automatically during initial setup. A luci server will first need to be installed and started either on one cluster node or a dedicated system:
# yum install luci
  • On all cluster nodes the ricci package must also be installed for the luci server to communicate with:
# yum install ricci

NOTE: Conga is not available in RHEL 7 or 8. Packages must be installed using yum on this release.

Installing Packages using yum

  • To manually install the High Availability / Clustering packages in RHEL 6, 7, 8 or 9:
# yum groupinstall 'High Availability'
  • To manually install the Resilient Storage packages in RHEL 6, 7, 8 or 9:
# yum groupinstall 'Resilient Storage'

NOTE: Each cluster node must use the same version of cluster-related packages. Ensure there is no version mismatch between cluster nodes.
