If we're swapping from a multiattach volume that has more than one read/write attachment, another server on the secondary attachment could be writing to the volume which is not getting copied into the volume to which we're swapping, so we could have data loss during the swap. This change does volume read/write attachment counting for the volume we're swapping from and if there is more than one read/write attachment on the volume, the swap volume operation fails with a 400 BadRequest error.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
