Expanding the Disk Capacity

Scenarios

If the system disk or data disk of a desktop pool or desktops in the desktop pool is insufficient, you can expand the disk capacity. This section describes how to expand the capacity of system disks or data disks for desktop pools and desktops in the pools.

Notes and Constraints

  • You can expand the capacity of a system disk or data disk only when the desktop pool is in the Running or Stopped status.
  • Only one disk can expand capacity in a desktop pool at a time.
  • The desktop will be restarted during disk capacity expansion.
  • During disk capacity expansion, the latest expansion snapshot will be deleted. The snapshot generated during the capacity expansion will be automatically deleted seven days later.
  • If desktops' disk sizes differ from the desktop pool's settings, you are advised to align them to ensure a consistent user experience. You can filter desktops with inconsistent disk sizes and expand the capacity of disks in batches.
  • The maximum capacity of a system disk is 1,020 GB. The capacity of a desktop can only be a multiple of 10. That is, the capacity of a system disk can be expanded only to 1,020 GB.
  • The maximum capacity of a data disk is 8,200 GB.

    The available capacity for expansion depends on the initial data disk size.

    • If the initial data disk size is less than 1,020 GB and the capacity of a desktop can only be a multiple of 10, the maximum data disk capacity is 1,020 GB. The excess capacity cannot be used.

      If a data disk needs to be expanded to over 1,020 GB, you must change the disk partition style from MBR to GPT. For details, see Data Disk Initialization. During the change, services will be interrupted and the original data will be cleared. Therefore, back up the data before changing the partition style.

    • If the initial data disk size is greater than 1,020 GB and the capacity of a desktop can be expanded only by a multiple of 10, the maximum data disk capacity is 8,200 GB.
  • For desktops in IES edge AZs, the available system disk and data disk capacity for expansion depends on the remaining resources in the AZs and must be an integer multiple of 10.
  • After the capacity of a Linux EVS disk is expanded, the disk will not be partitioned by default. For details about how to partition the disk, see Extending Disk Partitions and File Systems (Linux).

Procedure

You can expand the disk capacity in the following three scenarios. Select a scenario as required.

Expanding the Disk Capacity of a Desktop Pool

  1. Log in to the console.
  2. In the navigation pane, choose Desktops > Desktop Pools.

    The Desktop Pools page is displayed.

  3. You can access the page for expanding the disk capacity of a desktop pool in either of the following ways:

    • Method 1:
      1. Locate the desktop pool whose disks are to be deleted, and choose More > Disk > Expand Disk Capacity in the Operation column. The page for expanding disk capacity is displayed.
    • Method 2:
      1. On the desktop pool page, click the name of the desktop pool whose disk capacity is to be expanded. The basic information page of the desktop pool is displayed.
      2. Click Expand on the right of the Disk Information column in the desktop pool information. The page for disk capacity expansion is displayed.

  4. Select the applicable scope.

    • Only added desktops: The change is only applied to new desktops that are automatically or manually added to the desktop pool.
    • Added and idle desktops: The change is applied to new desktops that are automatically or manually added to the desktop pool and idle desktops (those not assigned to users) in the desktop pool.
    • Added and existing desktops: The change is applied to new desktops that are automatically or manually added to the desktop pool and all desktops in the desktop pool.

  5. Select System Disk or Data Disk.
  6. (Optional) If there are multiple data disks, select them as needed.
  7. Configure the Add Capacity (GB).
  1. Confirm the capacity expansion information, and enter YES or click Auto Enter.
  2. Click Next and click OK.

Expanding the Disk Capacity of a Desktop in a Static Pool

  1. Log in to the console.
  2. In the navigation pane, choose Desktops > Desktop Pools.

    The Desktop Pools page is displayed.

  3. Click the desktop pool name. The basic information page of the desktop pool is displayed.
  4. Locate the desktop and choose More > Disks and Snapshots > Expand Disk Capacity in the Operation column. The Expand Disk Capacity page is displayed.
  5. Select System Disk or Data Disk.
  6. (Optional) If there are multiple data disks, select the data disk to be expanded.
  7. Configure the Add Capacity (GB).
  1. Select I understand the impact of this operation and determine to expand the capacity.
  2. Click Next.
  3. Confirm the information and click OK.

Expanding the Disk Capacity of a Desktop in a Dynamic Pool

  1. Log in to the console.
  2. In the navigation pane, choose Desktops > Desktop Pools.

    The Desktop Pools page is displayed.

  3. Click the desktop pool name. The basic information page of the desktop pool is displayed.
  4. Click Disk Sizes Varied to filter desktops with different disk sizes.

    • Expanding the capacity of a single disk: Locate the desktop and choose More > Disk Management > Expand Disk Capacity in the Operation column. The Expand Disk Capacity page is displayed.
    • Expanding the capacity of disks in batches: Click More > Disks Management > Expand Disk Capacity above the list. The Expand Disk Capacity page is displayed.

  5. Select System Disk or Data Disk.
  6. Confirm the capacity expansion information, and enter YES or click Auto Enter.
  7. Click Next and click OK.
