Overview

This charm implements Cinder charm subordinate that enables and configures the Infinidat storage backend for use with Charmed Openstack.

This charm is intended to work next to charm-infinidat-tools which configures the environment for using iSCSI and FC.

Note

: The cinder-infinidat charm is currently in tech-preview.

Configuration

To display all configuration option information run juju config <application>. If the application is not deployed then see the charm's Configure tab in the Charmhub. Finally, the Juju documentation provides general guidance on configuring applications.

Deployment

The charm can be deployed through a bundle or manually like described below:

juju deploy cinder --channel <channel>
juju deploy cinder-infinidat --channel <channel>
juju add-relation cinder-infinidat:storage-backend cinder:storage-backend

Infinidat configuration option validation

The charm deploys to blocked state unless all the mandatory configuration options for the Infinidat storage backend are properly set in the charm. Refer to Configure tab in the Charmhub for more information.

TLS encryption support

The charm supports configuring encrypted communication with Infinidat API and installation of the CA certificates.

Refer to Configure tab in the Charmhub for more information.

High availability

The charm can be used to enable Infinidat backend in highly available Charmed Cinder deployments.

Deferred service events

This charm supports the deferred service events feature.

Operational or maintenance procedures applied to a cloud often lead to the restarting of various OpenStack services and/or the calling of certain charm hooks. Although normal, such events can be undesirable due to the service interruptions they can cause.

The deferred service events feature provides the operator the choice of preventing these service restarts and hook calls from occurring, which can then be resolved at a more opportune time.

See Deferred service events for more information on this feature.

Documentation

The OpenStack Charms project maintains two documentation guides:

• OpenStack Charm Guide: the primary source of information for OpenStack charms
• OpenStack Charms Deployment Guide: a step-by-step guide for deploying OpenStack with charms
