The Cinder 3.48 API provides a shared_targets and service_uuid field in the volume resource which tells the caller whether or not it should lock operations on that volume. This change adds that logic to the DriverVolumeBlockDevice attach and detach flows by first trying to get the volume at the 3.48 microversion and if that's not available, it simply falls back to get the volume the same as before. If 3.48 is available and the volume storage backend uses shared targets, we synchronize the attach/detach operations using the volume service_uuid, which is based on the storage backend and is also configurable by the deployer on the Cinder side. This is a nice to have protection for "normal" volumes but is really needed for multiattach volumes to be detached safely. See Cinder blueprint add-shared-targets-flag-to-volume for details.

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:
