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.

Increase storage quota for etcd

Available since MCC 2.24.4 (Cluster releases 15.0.3 and 14.0.3)

You may need to increase the default etcd storage quota that is 2 GB if etcd runs out of space and there is no other way to clean up the storage on your management or managed cluster.

To increase storage quota for etcd:

1. In the spec:providerSpec:value: section of cluster.yaml, edit the etcd:storageQuota value:

   kubectl --kubeconfig <pathToManagementClusterKubeconfig> -n <projectName> edit cluster <clusterName>
   

   Configuration example:

   apiVersion: cluster.k8s.io/v1alpha1
   kind: Cluster
   metadata:
     name: mycluster
     labels:
       kaas.mirantis.com/provider: baremetal
       kaas.mirantis.com/region: region-one
   spec:
     providerSpec:
       value:
         apiVersion: baremetal.k8s.io/v1alpha1
         kind: BaremetalClusterProviderSpec
         etcd:
           storageQuota: 4GB
   

   Caution

   You cannot decrease the storageQuota once set.

   Note

   The kaas.mirantis.com/region label is removed from all MOSK objects in 24.1. Therefore, do not add the label starting with this release. On existing clusters updated to this release, or if added manually, MOSK ignores this label.

2. Applies only to the following Cluster releases:

   • 15.0.3 (MOSK 23.2.2) or 14.0.3

   • 15.0.4 (MOSK 23.2.3) or 14.0.4 if you scheduled a delayed management cluster upgrade

   Before upgrading your management cluster to MCC 2.25.0 (Cluster release 16.0.0), configure LCMMachine resources of the cluster controller nodes as described in Container Cloud documentation: Release notes - Update notes.
