OpenStack is used too much, and it is common to encounter this situation: performing an operation on instance will be in the "error" state if it fails.

And at this point we can hardly do anything but delete instance.

The editor teaches you how to restore the instance of "error". Take the above situation as an example, after error, you can click the link of instance to see the specific reason of error in the details page.

You can see that an exception occurred during the execution of the resize operation, resulting in an error in the operation. In fact, this is not a fatal error, instance is not damaged, but also works properly. What we need to do now is to find a way to get instance back to normal.

Web GUI has no corresponding operation and can only be operated through the nova reset-state command line.

The use of reset-state is very straightforward, because instance is not the default admin project, so it needs to be specified through-- os-project-id. After successful execution, the state of the instance is reset to "active", and we can perform various regular operations on it again.
