# Longhorn notes # Longhorn notes
## Migration from NFS to Longhorn
1. Delete the workload, and delete the PVC and PVC using NFS.
2. Create Longhorn volumes as described below.
3. Copy NFS data from lewis.dmz to local disk.
4. Spin up a temporary pod and mount the Longhorn volume(s) in it:
```nix
{
pods.testje.spec = {
containers.testje = {
image = "nginx";
volumeMounts = [
{
name = "uploads";
mountPath = "/hedgedoc/public/uploads";
}
];
};
volumes = {
uploads.persistentVolumeClaim.claimName = "hedgedoc-uploads";
};
};
}
```
5. Use `kubectl cp` to copy the data from the local disk to the pod.
6. Delete the temporary pod.
7. Create the workload with updated volume mounts.
8. Delete the data from local disk.

While it seems handy to use a K8s StorageClass for Longhorn, we do *not* want to use that. While it seems handy to use a K8s StorageClass for Longhorn, we do *not* want to use that.
