Volumes Tied To a Consistency Group Can Be Deleted

[Mike Perez]

Volume delete allows a volume to be deleted, even though it's part of a consistency group. Discussed this with Xing, and this was a missing check and shouldn't be allowed. Additional patches will be giving the ability to remove a volume from a consistency group [1].

    Prevent deleting volumes in a consistency group

    Currently you have to destroy the consistency group if you want to
    delete these volumes. In the Kilo release, we'll have the ability to
    remove a volume from a consistency group, which then can be deleted.

Hi Mike

Can I know the reason why a volume in CG can't be deleted ? What's the thinking in this design?

Thanks

Tao

If a volume is part of a consistency group, might be an accident to remove it. You can first remove it from the consistency group, then delete the volume.
