How to transfer volumes between domains and projects using OpenStack CLI client on 3Engines Cloud🔗
Volumes in OpenStack can be used to store data. They are visible to virtual machines like drives.
Such a volume is usually available to just the project in which it was created. Transferring data stored on it between projects might take a long time, especially if such a volume contains lots of data, like, say, hundreds or thousands of gigabytes (or even more).
This article covers changing the assignment of a volume to a project. This allows you to move a volume directly from one project (which we will call source project) to another (which we will call destination project) using the OpenStack CLI in a way that does not require you to physically transfer the data.
The source project and destination project must both be on the same cloud (for example WAW3-2). They can (but don’t have to) belong to different users from different domains and organizations.
What We Are Going To Cover🔗
- Initializing transfer of volume
- Accepting transfer of volume
- Cancelling transfer of volume
