[GitHub] [cloudstack-terraform-provider] vdombrovski opened a new issue, #72: Support hot resize of disk
vdombrovski opened a new issue, #72:
URL: https://github.com/apache/cloudstack-terraform-provider/issues/72
Currently, whenever the size of a volume changes, the disk gets detached before resizing.
https://github.com/apache/cloudstack-terraform-provider/blob/main/cloudstack/resource_cloudstack_disk.go#L217
However Cloudstack 4.17 supports dynamic data disk resising without detaching it, which means we don't always need to detach / attach disk in certain cases (e.g. when only size changes). It would be cool to have this feature in the TF provider as well.

Hi There,
When we resize a disk, we noticed that although terraform says its 'modified', in reality, Terraform will unmount, destroy the volume, recreate a new one. (We have to manually reattach it back after).
Will his fix resolve this as well?
Also, can terraform mount a volume for us automatically? Or do we have to manually mount it oureselves all the time?

@vdombrovski
I have cross-checked the issue and disk resize is happening when you use a custom disk offering
Terraform is performing the resize operation :
```
# cloudstack_disk.test-disk will be updated in-place
~ resource "cloudstack_disk" "test-disk" {
id = "d5a695d5-7bd7-46f8-b63f-be81152584bf"
name = "test-disk"
~ size = 5 -> 10
tags = {}
# (6 unchanged attributes hidden)
}
```
Please make sure to use a custom disk offering
```
resource "cloudstack_disk" "default" {
name = "test-disk"
attach = "true"
disk_offering = "custom"
size = 50
virtual_machine_id = "server-1"
zone = "zone-1"
}
```

@btzq
Yes with fix the resize job will be done without any detach operation.
