What's new in Mirantis OpenStack 5.1.1

Nathan Trueblood - December 10, 2014
We are pleased to announce the general availability of Mirantis OpenStack 5.1.1. This maintenance release includes numerous defect fixes and improvements.

Key Improvements in Mirantis OpenStack 5.1.1

  • Icehouse: includes the latest OpenStack Icehouse 2014.1.3 release.
  • HA Deployment: numerous fixes and improvements to high availability (HA) deployments
  • Ceph Firefly: supports recent maintenance release of Ceph 0.80.7 “Firefly”
  • Fuel Master Upgrade: supports Fuel Master Node 5.1.1 upgrade and we’ve reduced the size of the upgrade download.

Additional improvements and fixes are described in our Release Notes.

For those of you who have already installed Mirantis OpenStack 5.1 and 5.01, you can upgrade your Fuel Master Node in place and retain management of your existing 5.0.1 and 5.1 environments. No need to redeploy! Just download the Upgrade Package and follow the instructions. After the upgrade, the Fuel Master Node can deploy a new Mirantis OpenStack 5.1.1 environment and manage existing 5.1 and 5.0.x environments.

We work openly in the community, and contribute our improvements; for more details about fixes you can visit our launchpad pages:

MOS 5.1.1 Launchpad bugs report (61 issues)
Fuel 5.1.1 Launchpad bugs report (19 issues)

The Mirantis QA team runs numerous test scenarios, derived from our customers and partners, across a broad variety of categories:

  • System tests. Confirm functionality and health of Mirantis OpenStack environment
    • Deployment Tests. Use Fuel to deploy OpenStack in a variety of different configurations and confirm functionality
    • Resiliency, Scalability and Operability Tests. Confirm cloud functionality (e.g. add a compute node), high-availability, reliability, scale, and load testing
    • Interoperability: Virtual deployment, bare-metal, hardware compatibility, partner integration testing
  • Scenario Tests. Corner cases and tricky scenarios
  • Defect fix verification. Confirm that issues with fixes are resolved.

We are constantly adding new categories and scenarios as we work closely with our customers and partners to deploy OpenStack in production.
