The sds-local-volume module: configuration

Enabling the module

To enable the sds-local-volume module, follow these steps:

1. Enable the sds-local-volume module:

   d8 k apply -f - <<EOF
   apiVersion: deckhouse.io/v1alpha1
   kind: ModuleConfig
   metadata:
     name: sds-local-volume
   spec:
     enabled: true
     version: 1
     settings:
       enableThinProvisioning: true # if you plan to use LVM-thin volumes
   EOF
   

2. Wait for the sds-local-volume module to transition to the Ready state:

   d8 k get modules sds-local-volume -w
   

3. Verify that the module pods are running:

   d8 k -n d8-sds-local-volume get pod -owide
   d8 k -n d8-sds-node-configurator get pod -o wide
   

For detailed module setup instructions, see the Quick start section.

parameters

Schema version: 1

• settings

  object
  • settings.dataNodes

    object

    Settings for local volumes csi on nodes with data

    Default: {}

    • settings.dataNodes.nodeSelector

      object

      The same as in the Pods spec.nodeSelector parameter in Kubernetes.

      If parameter is omitted, local volume csi will be placed on all nodes.

      Caution! Changing this parameter does not result in data redistribution. If node with data no longer matches the nodeSelector, data on that node will become inaccessible.

      Default: { "kubernetes.io/os": "linux" }

  • settings.enableThinProvisioning

    boolean

    Allow thin LVM volumes usage

    Default: false

  • settings.logLevel
