Abstract
Like in Chapter 4, a cluster resource must be created for every resource or application you run on the servers in your cluster. Cluster resources can include Web sites, e-mail servers, databases, file systems, virtual machines, and any other server-based applications or services you want to make available to users at all times.
You can either use the graphical HA Management Client utility, or the crm command line utility to create resources. This chapter introduces the several crm utilities.
After the installation there are several tools to administer a cluster.
Usually you need the crm command only. This command
has several subcommands. Run crm help
to get an overview of all available commands.
It has a thorough help system with embedded examples.
The crm tool has management abilities (the subcommands resources and node), and are used for configuration (cib, configure). Management subcommands take effect immediately, but configuration needs a final commit.
