When extending an in-use volume, the volume will be extended but the target exposing the volume will still report the original size. The target needs to be updated to pick up the change, but since it is in-use the update must be forced. This can cause IO disruption if there is active IO to the target, however retries will cause the next attempt to succeed and there will just be a few second IO pause on the host while the target session is reestablished. Not ideal, but it does recover with minimal impact on the host. And operators probably shouldn't extend volumes without pausing active IO to the volume anyway. See bug report comments for more testing details. Marking this as partial as it only addresses the tgt target and further investigation is needed to see if the other target drivers need similar updates.
