Expanding Capacity for an Available EVS Disk

Scenarios

This section describes how to expand the capacity of an Available EVS disk on the management console. The Available status indicates that the disk has not been attached to any server.

Constraints

  • Currently, disk capacities can only be expanded, but cannot be reduced.
  • A shared disk cannot be expanded in the In-use state. To expand a shared In-use disk, you must detach it from all its servers, wait until its status changes to Available, and then expand its capacity.

Procedure

  1. Log in to the management console.
  2. Under Storage, click Elastic Volume Service.

    The disk list page is displayed.

  3. In the disk list, locate the row that contains the target disk and click Expand Capacity in the Operation column.

    The expansion page is displayed.

  4. Set the Add Capacity (GiB) parameter and click Next.
  5. On the Details page, check the disk details.

    • If you do not need to modify the specifications, click Submit.
    • If you need to modify the specifications, click Previous.

    After the specifications are submitted, go back to the disk list page.

  6. In the disk list, view the capacity of the target disk.

    When the disk status changes from Expanding to Available and the disk capacity increases, the expansion has succeeded.

  7. Attach the disk to the server. For details, see Attach an EVS Disk.
  8. After the disk has been expanded on the management console, only the disk storage capacity is enlarged, but its additional space cannot be used directly. You must log in to the server and extend the disk partition and file system.

    The operation method varies depending on the server OS.
