10 Easy Steps to Create a New Cluster in an Existing RHEV Setup

10 Easy Steps to Create a New Cluster in an Existing RHEV Setup

Welcome to our blog on creating a new cluster in an existing Red Hat Enterprise Virtualization (RHEV) setup. In this guide, we will cover topics such as configuring hosts, creating virtual networks, and managing storage. By the end of this guide, you will have a solid understanding of how to create and manage a new cluster in RHEV, allowing you to expand your virtualization infrastructure and better meet the needs of your organization. So, let’s get started!

In this article, we will take a step-by-step look into how to go about the following:

  • Installing RHVH 4.3.7 image on two hypervisors
  • Configuring a network, bonding and validating the network
  • Creating separate clusters of new RHVH hosts
  • Creating new storage domains
  • Adding Nodesto RHEV

 

Note: The names and naming conventions used here are for demonstration purposes only, please change them as necessary

Step 1: 

  • Install RHEV4.3.7 ISO image on both the hypervisors
  • Install RHEV4.3.7 on both the hypervisors

Step 2: Validate both hosts after installation

      • RHVH-1

New cluster in RHEV - 3

New cluster in RHEV - 4

  • RHVH-2

New cluster in RHEV - 5

New cluster in RHEV - 6

New cluster in RHEV - 7

New cluster in RHEV - 8

Step 3: Check the Network and DNS

  • RHVH-1

New cluster in RHEV - 9

  • RHVH-2

New cluster in RHEV - 10

Step 4: Configure chrony on the hosts and validated them

  • RHVH-1

New cluster in RHEV - 11

  • RHVH-2

Step 5: Create a new cluster(here, we named it TCPAIMSCLU2)

Step 6: Add both the hosts in the new cluster

  • Adding RHVH-1 to the cluster

New cluster in RHEV - 16

New cluster in RHEV - 17

  • Add RHVH-2 to the cluster

New cluster in RHEV - 18

New cluster in RHEV - 19

Step 6: Configure the bond (mode-1) on both hosts

  • RHVH-1 bond configuration

New cluster in RHEV - 20

New cluster in RHEV - 21

  • Validate the bond after configuration

New cluster in RHEV - 22

New cluster in RHEV - 23

  • RHVH-2 bond configuration

New cluster in RHEV - 24

New cluster in RHEV - 25

  • Validate the bond after configuration

New cluster in RHEV - 26

New cluster in RHEV - 27

 

Creating Storage Domains

Step 7: Create a new storage domain (here, we named it RESS_websphere)

New cluster in RHEV - 28

Step 8: Create a new storage/OS domain

New cluster in RHEV - 29

 

Step 9: Create a new GFS2 storage domain (here, we named it RESS_GFS_DISK01)

New cluster in RHEV - 30

New cluster in RHEV - 31

 

Step 10: Validate all the newly created storage domains

New cluster in RHEV - 33

And that should be all you have to do!

Creating a new cluster in an existing RHEV setup can be a great way to expand the capabilities of your virtualization infrastructure. The process of adding new hosts, configuring virtual networks and managing storage can be challenging, but with the right steps, it can be done easily. By following the guidelines outlined in this blog, you should now have a better understanding of how to create and manage a new cluster in RHEV. With this knowledge, you can confidently take on new projects and improve the efficiency of your virtualization environment. We hope this blog has been helpful and informative, and we encourage you to continue learning and experimenting with RHEV to fully utilize its capabilities.
