scaleio openstack #4

Supports: xenial trusty precise

Description

ScaleIO OpenStack integration charm

Overview

This charm provides connection of ScaleIO cluster to OpenStack.

Its units should be placed in the same machines as scaleio-sdc and nova-compute or cinder or glance.

It should be connected to the ScaleIO Gateway and only service of this type should be present.

It prepares (configures and patches if required) nova-compute, cinder and glance to use ScaleIO as a block storage.

It supports both block storage volumes operations and nova ephemeral storage for instances including live migration.

Important: ScaleIO supports only 8gb increases for storage allocation so special flavors for storage in multiples of 8 should be created in OpenStack.

Important: scaleio-sdc charm should be installed on the same machine (host) as scaleio-openstack to serve nova-compute, cinder or glance.

Usage

The charm can be fetched from the JuJu charm-store.

Or it can be installed locally in the following manner:

  1. cd to directory where trusty/scaleio-openstack resides
  2. use command juju deploy local:trusty/scaleio-openstack

Example:

Deploy the connector juju deploy scaleio-openstack

Configure protection domains and storage pools juju set scaleio-openstack protection-domains="pd1" storage-pools="sp1"

Connect it to the Gateway juju add-relation scaleio-gw scaleio-openstack

Configuration

  • protection-domains - Comma-separated list of protection domains
  • storage-pools - Comma-separated list of storage pools
  • provisioning-type - Volume provisioning type thin or thick
  • verify-server-certificate - Verify server certificate while connecting to ScaleIO Gateway from nova/cinder code parts
  • server-certificate-path - Certificate path for validating server certificate
  • round-volume-capacity - Round up volume capacity or not while creating. Only Cinder's option.

Relations

Should be related to scaleio-gw. Reconfiguration of OpenStack is done when relation is set.
