Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set will cover all product layers, including MOSK management (formerly MCC). This means everything you need will be in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Known issues¶

This section describes the patch-related known issues with available workarounds.

OpenStack upgrade failure¶

Fixed in MOSK 23.1.3

The OpenStack upgrade to Yoga fails due to the delay in the Cinder start.

Workaround:

Follow the openstack-controller logs from the OpenStackDeployment container. When the controller is stuck on checking health for any OpenStack component, verify the Helm releases statuses:

helm3 --namespace openstack list

Example of a system response:

NAME                     NAMESPACE       REVISION        UPDATED                                 STATUS          CHART
openstack-cinder         openstack       111             2023-04-30 20:49:08.969450386 +0000 UTC failed          cinder-0.1.0-mcp-4241

If there is a release in the failed state, roll it back:

helm3 --namespace openstack rollback openstack-cinder
