terraform plan showing diff after import of GCE persistent disk

Question

I had to restore a GCE persistent disk from snapshot. Now I wanted to import the new disk to terraform.

So I did:

terragrunt import google_compute_region_disk.region_disk projects/my-project/regions/australia-southeast1/disks/ops-syd-jenkins-00

This works as I can correct snapshot id in remote state file. So, state file is refreshed fine. However when I do terragrunt plan, it shows me the difference and wants to delete my existing disk.

Terraform will perform the following actions:

  # google_compute_region_disk.region_disk will be destroyed
  - resource "google_compute_region_disk" "region_disk" {
      - creation_timestamp        = "2022-03-15T18:11:16.301-07:00" -> null
      - id                        = "projects/my-project/regions/australia-southeast1/disks/ops-syd-jenkins-00" -> null
      - label_fingerprint         = "nT7_dAxskBs=" -> null
      - labels                    = {
          - "goog-gke-volume" = ""
        } -> null
      - last_attach_timestamp     = "2022-03-15T18:13:37.907-07:00" -> null
      - name                      = "ops-syd-jenkins-00" -> null

        ] -> null

      - timeouts {}

      + users                     = (known after apply)
    }

Plan: 1 to add, 0 to change, 1 to destroy.

Not sure what I am doing wrong. Thanks.

My bad, it was a bad import. Needed to run following to import:

terragrunt import google_compute_region_disk.region_disk["ops-syd-jenkins-00"] projects/my-project/regions/australia-southeast1/disks/ops-syd-jenkins-00
