Cinder supports volume transfers, which are transfers of ownership from one project to another. The normal flow is that a donor creates a volume transfer, captures the resulting transfer id and secret authentication key, and passes that information out of band to the recipient (such as by email, text message, etc.). The recipient then accepts the transfer, supplying the transfer id and authentication key. The ownership of the volume is then transferred from the donor to the recipient, and the volome is no longer visible to the donor. It is important to know of some limitations about the cinder API for volume transfers and their impact on the UI design. 1. When creating a volume transfer, you cannot specify who the intended recipient will be, and anyone with the transfer ID and auth key can claim the volume. Therefore there is no UI to prompt for a recipient. 2. Current volume transfers are only visible to the donor; users in other projects are unable to view these transfers. This makes it pointless to create a project table to view and accept volume transfers, since the current transfers are not visible. Instead, the transfer information has been added to the volume details, which are visible by the donor, and the volume state clearly reflects that a transfer has been created. It it also impossible to present to the recipient a pull-down list of transfers to accept. 3. The only time that the authorization key is visible to the donor is in the response from the creation of the transfer; after creation it is impossible for even the donor to recover it. Since the donor must capture the transfer ID and authorization key in order to send it to the recipient, an extra form was created to present this information to the donor immediately after the transfer has been created. It is not enough to put the information in a success message, since these are typically only displayed for a small number of seconds before they disappear. Co-Authored-By: Gary W.
