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 I have tree simple questions about LVM that just could not be answered after 4 hours of search in LVM howto, Google, Linux questions and linux-lvm Archives. I have a small file server with 600Gbytes in one liner volume group consisting of 3 200 Gbyte Hard disk. My questions are: 1. If one hard disk fails (hardware) do I loose all the data stored on the VG? 2. Can I add a new hard disk in the VG without having to format it before? (I mean if it is full of data can I just add it?) 3. In case of failure can I recover the data from a single disk on another box? Thanks in advance Kyriakos Greece
