Terraform Version

Terraform v1.9.6
on linux_amd64
+ provider registry.terraform.io/hashicorp/archive v2.6.0
+ provider registry.terraform.io/hashicorp/local v2.5.2
+ provider registry.terraform.io/scaleway/scaleway v2.47.0

Affected Resource(s)

• scaleway_instance_server

Terraform Configuration Files

resource "scaleway_instance_server" "worker" {
  for_each = var.worker_servers
  type = each.value.instance_type
  image = each.value.image
  ip_id = scaleway_instance_ip.public_ip[each.key].id
  name = each.key
  tags = each.value.tags
  root_volume {
    volume_type = each.value.volume_type
    size_in_gb = each.value.volume_size
  }
  private_network {
    pn_id  = scaleway_vpc_private_network.vpc.id
  }
}

Expected Behavior

I expect it to replace the volume size with the new one

Actual Behavior

When I do
terraform plan -target=scaleway_instance_server
it show me this:

Terraform will perform the following actions:

  # scaleway_instance_server.worker["xxxxxx"] must be replaced
-/+ resource "scaleway_instance_server" "worker" {
      - additional_volume_ids            = [] -> null

      - public_ips {
          - address = "xxxxxxxxx" -> null
          - id      = "xxxxx" -> null
        }

          ~ size_in_gb            = 20 -> 50 # forces replacement
          ~ volume_id             = "xxxxxxxxx" -> (known after apply)
            # (3 unchanged attributes hidden)
        }
    }

Hello,

Currently we do not support the update of the size of volumes. I have just created a ticket to add this feature
#2838.

Thank you for your feedback,

Have a nice day,
