Cloudsnap restores to pvc without stork

1

Due to a conflict with a piece of software we use on our cluster, we weren’t able to use Stork for the portworx installation. I’m testing cloudsnap backups right now, and I can restore a volume to a new volume name, but at that point, I’m not sure how to get that back into kubernetes as a usable storage area.

We’re using the CSI provisioner to attach to our pure flash array, if that’s any help for any commands to run to get things hooked up again.

Is there any way to do this without the use of Stork?

Thanks.

I think I actually got this to work in this way:

  • restore the volume using pxctl cloudsnap restore
  • create a PV and PVC to re-create a volume in kubernetes. The PV definition looks similar to:
apiVersion: v1
kind: PersistentVolume
metadata:
  annotations:
    pv.kubernetes.io/provisioned-by: pxd.portworx.com
    volume.kubernetes.io/provisioner-deletion-secret-name: ""
    volume.kubernetes.io/provisioner-deletion-secret-namespace: ""
  name: restoretest
spec:
  accessModes:
  - ReadWriteMany
  capacity:
    storage: 50Gi
  claimRef:
    apiVersion: v1
    kind: PersistentVolumeClaim
    name: restored-volume
    namespace: test-project1
  csi:
    driver: pxd.portworx.com
    fsType: ext4
    volumeAttributes:
      attached: ATTACH_STATE_INTERNAL_SWITCH
      error: ""
      parent: ""
      readonly: "false"
      secure: "false"
      shared: "true"
      sharedv4: "false"
      state: VOLUME_STATE_DETACHED
      storage.kubernetes.io/csiProvisionerIdentity: 1698839449476-4689-pxd.portworx.com
    volumeHandle: "288397840309906678"
  persistentVolumeReclaimPolicy: Delete
  storageClassName: portworx
  volumeMode: Filesystem
  • the volumeHandle should be replaced with the volume ID presented by pxctl volume list

The PVC definition that gets created is pretty straightforward after that, just making sure that the name/namespace/storagesize matches what was in the PV definition.

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  namespace: test-project1
  name: restored-volume
spec:
  storageClassName: portworx
  volumeName: restoretest
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 50Gi
