Resize a Portworx PVC in OCP GCP
This document describes how to dynamically resize a volume (PVC) using OpenShift and Portworx.
Pre-requisites
- The StorageClass must have
allowVolumeExpansion: true
. - The PVC must be in use by a Pod.
Example
To resize a Portworx PVC, you can simply edit the PVC spec and update the size. Let's take an example of resizing a MySQL PVC.
-
Download the MySQL StorageClass spec and apply it. Note that the StorageClass has
allowVolumeExpansion: true
. -
Download the MySQL PVC spec and apply it. We will start with a 5GB volume.
-
Download the MySQL Deployment spec, specify your own values for the
ACCEPT_EULA
andSA_PASSWORD
, and apply it. Wail till the pod becomes 1/1 and then proceed to next step. -
Run
kubectl edit pvc mssql-data
and change the size in the "spec" to 10Gi.
After you save the spec, kubectl describe pvc mssql-data
should have an entry like below that confirms the volume resize.
