Disks

Purpose

• Create virtual disks and attach them to a VM.
• Increase (grow) an existing disk's size.
• See each disk's storage pool placement, size, and attached VM.
• Remove disks that are no longer needed.

Prerequisites

• Minimum permission to view: compute.disks.read
• To create a disk: compute.disks.create
• To edit or resize a disk: compute.disks.update
• To delete a disk: compute.disks.delete
• At least one storage pool that accepts VM disks must exist before you can create a disk.
• Disks live on storage pools; disk operations run asynchronously and complete via Task Manager (top bar).

View disks

1. Open Compute → Disks.
2. Review each disk's size, storage pool, and attached VM.
3. Select a disk to open its detail page and utilisation.

Create and attach a disk

1. Open Compute → Disks.
2. Select Create Disk (disabled until a storage pool exists).
3. Choose the VM to attach the disk to.
4. Enter a disk name and a whole-number size in GB.
5. Select the storage pool to place the disk on.
6. Optionally inherit the VM's tags, or set tags and a resource group.
7. Save.

Expected result: a disk task is queued in Task Manager and the disk attaches to the VM once the worker completes.

Resize or edit a disk

1. Open Compute → Disks and open a disk.
2. Select Edit.
3. Update the name, description, or storage pool.
4. Increase the size in GB — size can only be increased, never reduced.
5. Save.

Expected result: the disk update is queued in Task Manager.

Delete a disk

1. Open Compute → Disks.
2. Select one or more disks and choose Delete, or open a disk and select Delete.
3. Confirm in the dialog.

Expected result: a disk-delete task is queued in Task Manager.

Best Practices

• Size disks in whole GB within the target storage pool's available capacity.
• Attach a disk to its VM at creation so tags can inherit from the VM.
• Increase disk size only when required — reductions are not supported.
• Confirm the delete task completes in Task Manager before assuming space is freed.
