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: linux-lvm@redhat.com Hi list, what now worked: - creating a cached data-lv - creating a non-cached meta-lv - converting data-lv to a thinpool-device with meta-lv as metadata what not: doing the same thing with a cached meta-lv. Does this make sense? Is the metadata already cached by lvm-logic? Do i have a cache thinpool (with non-cached metadata) with the used way? Tfh!
