Learn how to change a block storage volume type from Classic or High speed to High speed gen2.

 

Requirements

 

Instructions

When trying to change a block storage volume type to "High speed gen2," the migration policy will need to be changed from Never to On-demand.

The migration policy is set by default to Never as the volume stays on the same CEPH cluster. However, for the "High speed gen2" type, the volume will need to be migrated to a new cluster.

This modification can be made via Horizon or the OpenStack CLI.

 

From the Horizon Interface

Log in to the Horizon interface and make sure you are in the correct region. You can verify this in the top left corner.

Next, open the Volumes menu on the left side and click on Volumes. Find the row for your volume in the table, click on the drop-down arrow next to Edit Volume, and select Change Volume Type.

In the pop-up window:

  • For Type, select high-speed-gen-2.
  • For Migration Policy, select On Demand.

Once done, click on Change Volume Type to confirm the change.

From the OpenStack CLI

NOTE: Make sure to consult the following guide before proceeding: Preparing an environment for using the OpenStack API.

First, list the type of volumes available in your region with the following command:

#~$ openstack image list
+--------------------------------------+-----------------------------------------------+----------+
| ID                                   | Name                                          | Is Public|
+--------------------------------------+-----------------------------------------------+----------+
| 27844ef7-1a9a-4944-be59-6e4eb19a71f6 | high-speed-gen2                               |      True|
| 23f75fef-d4f6-416a-a884-95aa3fd45695 | classic                                       |      True|
| 2f78e8af-93c9-4e5c-b177-83c4a7ec456a | high-speed                                    |      True|
----------------------------------------------------------------------------------------------------

NOTE: Please note that if the volume type "high-speed-gen2" does not appear in the list, it means that it is not available in this region.

Next, switch volume types with the following command:

$ openstack volume set --type high-speed-gen2 --retype-policy on-demand VOLUME_NAME_OR_ID
