Managing Red Hat Gluster Storage using the Web Console

Red Hat Hyperconverged Infrastructure for Virtualization 1.8

Perform common Red Hat Gluster Storage management tasks in the Web Console

Laura Bailey

Abstract

After Red Hat Hyperconverged Infrastructure for Virtualization has been deployed, you can perform many operational and management tasks for Red Hat Gluster Storage using the Web Console. Read this book to understand how to manage storage using the Web Console.
This document explains how to perform maintenance tasks specific to Red Hat Hyperconverged Infrastructure for Virtualization.

Making open source more inclusive

Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.

    Configure this from the node that is running the Web Console to all new nodes, and from the first new node to all other new nodes.

    Important

    RHHI for Virtualization expects key-based SSH authentication without a password between these nodes for both IP addresses and FQDNs. Ensure that you configure key-based SSH authentication between these machines for the IP address and FQDN of all storage and management network interfaces.

    Follow the instructions in Using key pairs instead of passwords for SSH authentication to configure key based authentication without a password.
