# Image Statuses

Images in Glance can be in one of the following statuses:

- `queued`

  The image identifier has been reserved for an image in the Glance registry. No image data has been uploaded to Glance and the image size was not explicitly set to zero on creation.

- `saving`

  Denotes that an image’s raw data is currently being uploaded to Glance. When an image is registered with a call to POST /images and there is an x-image-meta-location header present, that image will never be in the saving status (as the image data is already available in some other location).

- `uploading`

  Denotes that an import data-put call has been made. While in this status, a call to PUT /file is disallowed. (Note that a call to PUT /file on a queued image puts the image into saving status. Calls to PUT /stage are disallowed while an image is in saving status. Thus it’s not possible to use both upload methods on the same image.)

- `importing`

  Denotes that an import call has been made but that the image is not yet ready for use.

- `active`

  Denotes an image that is fully available in Glance. This occurs when the image data is uploaded, or the image size is explicitly set to zero on creation.

- `deactivated`

  Denotes that access to image data is not allowed to any non-admin user. Prohibiting downloads of an image also prohibits operations like image export and image cloning that may require image data.

- `killed`

  Denotes that an error occurred during the uploading of an image’s data, and that the image is not readable.

- `deleted`

  Glance has retained the information about the image, but it is no longer available to use. An image in this state will be removed automatically at a later date.

- `pending_delete`

  This is similar to deleted, however, Glance has not yet removed the image data. An image in this state is not recoverable.

This is a representation of how the image move from one status to the next.

- Add location from zero to more than one.

# Task Statuses

Tasks in Glance can be in one of the following statuses:

- `pending`

  The task identifier has been reserved for a task in the Glance. No processing has begun on it yet.

- `processing`

  The task has been picked up by the underlying executor and is being run using the backend Glance execution logic for that task type.

- `success`

  Denotes that the task has had a successful run within Glance. The `result` field of the task shows more details about the outcome.

- `failure`

  Denotes that an error occurred during the execution of the task and it cannot continue processing. The `message` field of the task shows what the error was.
