Resizing an instance using OpenStack terminal client¶

Important

Resizing an instance will cause the instance to shut off during the process. We recommend doing a backup of your data before proceeding.

Identify the flavor you want. You can list all flavors with openstack flavor list.
Identify the instance you want to resize. You can list all your instances with openstack server list.
To resize, run the following command: openstack server resize --flavor [FLAVOR NAME] [INSTANCE NAME] where you replace the items in brackets to the flavor you choose in previous step and the instance name.
Run the command: openstack server list and you’ll see the instance is now in Status VERIFY_RESIZE. Login to the instance and verify that it worked as intended (meaning the instance is working as before but with the new flavor).
If you are happy with the result, confirm the resize with openstack server resize confirm [INSTANCE NAME], this completes the process and make the resize permanent.
If you are unhappy (or for some reason the resize was unsuccessful), you are able to instead run the command openstack server resize revert [INSTANCE NAME]. This will revert the process.

The process is now complete.
