That's because you have not tried to recover an LVM. I had one with Raid1 and when drive1 failed, Boot was on disk 0. I was hoping to able to boot from disk 0 then to put a new disk next day... To make a short story even shorter, no go. I had to restore from a 3 days old backup. LVMs are very convenient for adding new drive and making them larger. I don't know of a live-CD that supports LVMs. -- Thanks http://www.911networks.com When the network has to work
