Chapter 9. Using the Gluster Command Line Interface

The Gluster command line interface (CLI) simplifies configuration and management of the storage environment. The Gluster CLI is similar to the LVM (Logical Volume Manager) CLI or the ZFS CLI, but operates across multiple storage servers. The Gluster CLI can be used when volumes are mounted (active) and not mounted (inactive). Red Hat Gluster Storage automatically synchronizes volume configuration information across all servers.

Use the Gluster CLI to create new volumes, start and stop existing volumes, add bricks to volumes, remove bricks from volumes, and change translator settings. Additionally, the Gluster CLI commands can create automation scripts and use the commands as an API to allow integration with third-party applications.

Run commands directly as follows, after replacing COMMAND with the required command:

gluster COMMAND

# gluster COMMAND

The following is an example using the peer status command:

gluster peer status

# gluster peer status

gluster

# gluster

If successful, the prompt changes to the following:

gluster>

gluster>

When the prompt appears, execute gluster commands from the CLI prompt as follows:

gluster> COMMAND

gluster> COMMAND

As an example, replace the COMMAND with a command such as peer status to view the status of the peer server:

The following is another example, replacing the COMMAND with a command such as help to view the gluster help options.
