./attach-detach.sh detach pvc my-vcluster -n my-vcluster-namespace

kubectl delete pvc data-my-vcluster-0

Next start vCluster and restore the objects within the vCluster (statefulsets etc.)

# Attach all pvc's of vCluster called "my-vcluster" in namespace "my-vcluster-namespace"
./attach-detach.sh attach pvc my-vcluster -n my-vcluster-namespace
