Expanding an Available Disk

Scenarios

Currently, disk capacities can be expanded, but cannot be reduced.

Expanding an Available disk means that the to-be-expanded disk has not been attached to a server.

Procedure

  1. Log in to the management console.
  2. Choose Dedicated Distributed Storage Service > Disks.

    The disk list page is displayed.

  3. (Optional) If the to-be-expanded disk has been attached to a server, detach it first. For details, see Detaching a Disk.

    When the disk status changes to Available, the disk is successfully detached.

  4. 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.

  5. Set the Add Capacity (GB) parameter as prompted and click Next.
  6. On the Details page, check the disk information again.

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

    After the specifications are submitted, the disk list page is displayed.

  7. In the disk list, view the capacity of the expanded disk.

    After the disk status changes from Expanding to Available, the additional capacity has been added to the disk and the expansion succeeded.

    If the disk status is Expanding, you are not allowed to modify the specifications of the ECS where the disk is attached.

  8. Attach the expanded disk to a server. For details, see the following topics:

  9. After the capacity expansion has succeeded, perform subsequent operations for the additional space.

    The operation method varies depending on the server OS.
