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"; format="flowed" To: linux-lvm@redhat.com Hi list, im wondering, that on the lvcreate man-page stands "specifying -i3 would use 3 devices for striped logical volumes, 4 devices for RAID 4/5, and 5 devices for RAID 6" Imho there is a Raid-5 device with 3 disks possible. Is there an error in the documentation or does lvm need more stripes for Raid-5 than normally used? Tfh! Oliver
