Reply-To: LVM general discussion and development List-Id: LVM general discussion and development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , List-Id: Content-Type: text/plain; charset="us-ascii" To: LVM general discussion and development Hi list, if I create a snapshot of a volume in a thinpool, first only metadata need space. Later, through copy-on-write, the real needed size grows. Is it possible to get this size? Tfh! Oliver
