How to mount new volume in Kubernetes Pod

I have a Velero backup going that produces volume snapshots of our production environment. Now I need to load and copy the data from one of these snapshots, in a test environment. Basically, I want to copy the state from production, but can’t do a full Velero restore. I created a volume from the snapshot and was asked to attach it to a droplet, so I chose one of the test K8s cluster’s nodes. This all seems fine, but I can’t figure out how to make this volume available to a pod. I have a test pod, which I can attach to the existing k8S volumes by setting it up with existing PersistedVolumeClaims. These are existing volumes created using PVCs. For the new volume, I tried to duplicate and modify the exists PVC, replacing the volume name/id with the one I configured in the DO web. Then I tried to start the pod with this configuration. However, K8s says the pod and the PVC failed because the PVC in “unbound” / “ClaimLost”. In any case, I guess the test pod must run on the cluster node where I assigned the volume.

Any advice on how to mount a new DO volume, containing restored data, onto a K8s pod?
