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. This can be done by running command: openstack flavor list.
Identify the instance you want to resize. This can be done by running the following command: 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, run the following command: openstack server resize confirm [INSTANCE NAME] This will finalize the process and make it permanent.
If you are unhappy (for some reason the process failed), you are able to instead run the command openstack server resize revert [INSTANCE NAME]. This will revert the process.

The process is now complete.
