Adding extra persistent volume mount to Pod

K8ssandra help
1

I want to mount a PV into the Cassandra pod. PV and PVC exist. Where must I add these lines so that the cassandra operator modifies the running pods ?

volumeMounts:

    - name: blob01

      mountPath: /mnt/blob

I need to mount an Azure Blobstore this way so that a restore script sees the content at /mnt/blob.
Cheers
