Answer when you create the LV using "lvcreate" use the -m option to set the number of mirror copies. Alturnatively you can use lvconvert to change a normal LV into a mirrored one. The question of how to get the system back if a disk fails in a tricky one.... If a disk fails the system should keep on working as there is a copy of the information so it will continue to work, Hardware might have problems with the drive if it is not a clean failure though, what is needed is to reduce out the damaged disk and add a new undamaged one, the one problem is the BOOT block if the disk is the boot device, then you might need use grub to setup a new boot block on the new device.
