Resizing an instance using OpenStack Horizon¶

Important

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

Under Project, click Compute and then Instances in the sidebar menu.
In the dropdown menu to the far right of the line corresponding to the instance you want to resize, press Resize instance.
Under New flavor, select the flavor you want.
Press Resize button.
You will see the status of the resize in the following page.
When it says Confirm or Revert Resize/Migrate, 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, press Confirm Resize/Rigrate in dropdown to the far right (it should be pre-selected). This will finalize the process and make it permanent.
If you are unhappy (for some reason the process failed), you are able to instead press Revert resize/Migrate (available in the dropdown). This will revert the process.

The process is now complete.
