Expanding the Disk Capacity

Scenario

If the capacity of the system disk or data disk used for purchasing a desktop pool is insufficient, you can expand the disk capacity.

Expand the capacity of a system disk or data disk in a desktop pool.

Prerequisites

You can expand the capacity of a system disk or data disk only when the desktop pool is in the Running or Stopped status.

Procedure

1. Log in to the console.
2. In the navigation pane, choose Desktop Management > Desktop Pool.

   The Desktop Pool 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:

   Locate the row that contains the desktop pool in which disk capacity is to be expanded, click More > Disk > Expand Disk in the Operation column. The page for disk capacity expansion is displayed.

   Method 2:

   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.

   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 System Disk or Data Disk as required.
5. (Optional) If there are multiple data disks, select the data disk to be expanded.
6. Configure the Add Capacity (GB).
   NOTE:

   • The maximum capacity of a system disk is 1020 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 1020 GB.
   • The maximum capacity of a data disk is 8200 GB.

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

     • If the initial data disk size is less than 1020 GB and the capacity of a desktop can only be a multiple of 10, the maximum data disk capacity is 1020 GB. The excess capacity cannot be used.

       If a data disk needs to be expanded to over 1020 GB, you must change the disk partition style from MBR to GPT (for details, see Initialization Overview). 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 1020 GB and the capacity of a desktop can be expanded only by a multiple of 10, the maximum data disk capacity is 8200 GB.
   NOTE:

   • Only one disk can expand capacity in a desktop pool at a time.
   • 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.
   • The desktop will be restarted during disk capacity expansion.
   • 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).

7. Select I understand the impact of this operation and determine to expand the capacity.
8. Click Next.
9. Confirm the information and click OK.
