Supports: xenial trusty precise

Add to new model

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.
