Create PVCs using the ReadOnlyMany access mode in Tanzu

This guide provides steps for mounting a disk in the ReadOnlyMany (ROX) access mode. The in-tree Portworx driver for Kubernetes does not support creating PVCs with the ReadOnlyMany access mode. To achieve this functionality, follow the steps below:

1. Create a sharedv4 volume. Note that you can access a sharedv4 volume from multiple pods at the same time. For details about creating a sharedv4 volume, refer to the Create sharedv4 PVCs page.

2. Add a persistentVolumeClaim subsection to the volumes section of your Pod, specifying the following fields and values:

   • readOnly: with the true value

   • claimName: with the name of the PVC you created in the step above
