The KNOWN flag will be true if the the EXISTS flag is meaningful. That is: KNOWN EXISTS ----- ------ 0 0 don't know whether the object exists 0 1 (not used/invalid) 1 0 object is known to not exist 1 0 object is known to exist This will be used in determining how to handle write requests for data objects for layered rbd images.
