Increase storage quota for etcd¶
Available since 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:
In the
spec:providerSpec:value:
section ofcluster.yaml
, edit theetcd: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: openstack kaas.mirantis.com/region: region-one spec: providerSpec: value: apiVersion: openstackproviderconfig.k8s.io/v1alpha1 kind: OpenstackClusterProviderSpec etcd: storageQuota: 4GB
Caution
You cannot decrease the
storageQuota
once set.Note
The
kaas.mirantis.com/region
label is removed from all Container Cloud objects in 2.26.0 (Cluster releases 17.1.0 and 16.1.0). Therefore, do not add the label starting these releases. On existing clusters updated to these releases, or if manually added, this label will be ignored by Container Cloud.Applies only to the following Cluster releases:
15.0.3 or 14.0.3
15.0.4 or 14.0.4 if you scheduled a delayed management cluster upgrade
Before upgrading your management cluster to 2.25.0, configure
LCMMachine
resources of the cluster controller nodes as described in Configure managed clusters with the etcd storage quota set.
