Manage Storage Disk

The Storage Disk tab on the Instance detail page lets you view and manage all disks attached to the Instance, including: adding new disks, editing disk information, deleting disks, creating Snapshots, and attaching Tags.

Note: Some features are only available depending on the VPC type the Instance belongs to. Specific VPC and General VPC have different options — see the details in each section below.

View the Disk List​

  1. Go to the Instance detail page.
  2. Select the Storage Disk tab.

The list displays all disks currently attached to the Instance with the following information:

Add a New Disk​

You can add a disk to an Instance while it is running or stopped.

  1. In the Storage Disk tab, click Add disk.
  2. Select the appropriate Storage Policy.
  3. Enter the disk capacity (GB).
  4. Click Confirm.

Add new disk screen

After adding, the new disk appears in the list. You need to go into the Instance's operating system to mount and use this disk.

Edit a Disk​

  1. In the Storage Disk tab, find the disk to edit.
  2. Click the Edit icon (or select Edit from the action menu).
  3. Change the necessary fields:
    • Disk name: change the display name.
    • Storage Policy: change the storage policy.
    • Capacity (GB): increase the disk size.
  4. Click Save to apply the changes.

Edit disk screen

Note: Disk capacity can only be increased, not decreased. After successfully increasing the capacity, you need to go into the Instance's operating system to expand the corresponding partition.

Delete a Disk​

You can delete a disk even while the Instance is running.

Warning: Deleting a disk will permanently erase all data on that disk. This operation cannot be undone. Back up your data before deleting.

Note: The root disk cannot be deleted.

For Specific VPC: You can delete local disks. The root disk can only be edited, not deleted.

For General VPC: You can delete external disks. The root disk cannot be deleted.

Steps to delete a disk:

  1. In the Storage Disk tab, find the disk to delete.
  2. Open the action menu and select Delete.
  3. Read the warning and confirm the operation.

Create a Snapshot for a Disk (General VPC)​

Note: This feature is only available in General VPC.

You can create a Snapshot for an external disk or a root disk directly from the Storage Disk tab.

  1. In the Storage Disk tab, find the disk to snapshot (root or external disk).
  2. Open the action menu and select Create Snapshot.
  3. Enter a name for the Snapshot.
  4. Click Confirm.

Create Snapshot from the Storage Disk tab

Snapshots are created asynchronously. After completion, you can view the Snapshot in the system's Snapshot management section.

Note: A disk Snapshot created from the Storage Disk tab is different from a full Instance Snapshot (FR-38). A disk Snapshot only saves the state of a specific disk.

Attach Tags to the Root Disk (General VPC)​

Note: This feature is only available for the root disk in General VPC.

You can attach Tags to the root disk for classification, search, and resource management purposes.

  1. In the Storage Disk tab, find the root disk.
  2. Open the action menu and select Manage Tags.
  3. Add or remove Tags as needed.
  4. Click Save to apply.
