Expand volume

You can expand the storage volume size of each pod.

Before you start​

Check whether the cluster status is Running. Otherwise, the following operations may fail.

kbcli cluster list mycluster
>
NAME        NAMESPACE   CLUSTER-DEFINITION   VERSION        TERMINATION-POLICY   STATUS    CREATED-TIME
mycluster   default     mysql                mysql-8.0.33   Delete               Running   Jul 05,2024 18:46 UTC+0800

Steps​

  1. Change configuration.

    Configure the values of --components, --volume-claim-templates, and --storage, and run the command below to expand the volume.

    kbcli cluster volume-expand mycluster --components="mysql" \
    --volume-claim-templates="data" --storage="2Gi"
    • --components describes the component name for volume expansion.
    • --volume-claim-templates describes the VolumeClaimTemplate names in components.
    • --storage describes the volume storage size.

  1. Validate the volume expansion operation.

    kbcli cluster list mycluster
    >
    NAME        NAMESPACE   CLUSTER-DEFINITION   VERSION        TERMINATION-POLICY   STATUS    CREATED-TIME
    mycluster   default     mysql                mysql-8.0.33   Delete               Running   Jul 05,2024 18:46 UTC+0800
    • STATUS=Updating: it means the volume expansion is in progress.
    • STATUS=Running: it means the volume expansion operation has been applied.

  2. Check whether the corresponding resources change.

    kbcli cluster describe mycluster
