google_compute_snapshot - Snapshot cannot be created for Regional disks (google_compute_region_disk)

Affected Resource(s)

• google_compute_snapshot

Hi team,

I was not able to create a Snapshot for Regional disks created with google_compute_region_disk.

google_compute_snapshot is not able to find the source disk for Regional disks as it is specifically searching for a disk inside project/<project_name>/zones/<zone_name>/disks/<disk_name> while regional disks are created inside project/<project_name>/regions/<region_name>/disks/<disk_name>

Also, the zone is a mandatory attribute now. Is that really intended?

Please check the screenshot attached below:

1. Cannot find regional disk which was created in the previous step
   
2. Zone is mandatory
   

Is there any other way of creating a snapshot for a Regional persistent disk or am I missing something? Please help.

Thanks in advance

@maheshwara-bwd what is your provider version ?, Hope this doc helps - https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/compute_region_disk

Hi @venkykuberan,

Thanks for the quick reply.
The document like you have shared is compute_region_disk which is used to create a Regional disk from snapshot or other sources.
But my requirement is to create a Snapshot out of the Regional disk. I can create a snapshot of the Zonal disk with google_compute_snapshot but not of a Regional disk.
The issue is google_compute_snapshot is not able to find the source disk for Regional disks as it is specifically searching for a disk inside project/<project_name>/zones/<zone_name>/disks/<disk_name> while regional disks are created inside project/<project_name>/regions/<region_name>/disks/<disk_name>
Please refer to the screenshots attached in the previous comment.

My provider version is 3.66

Are you referring the source_disk by name ?, if so can you try id/self_link of the resource ?

@maheshwara-bwd currently this resource supports only zonal disk snapshot code , we may need a new resource for regional disks or modify the existing one to support both. I will mark this issue as an enhancement and will take it from there. Thanks for filing the issue
