I have several old hard disks laying around the house, and I want to make a spanned volume (some may call it JBOD, but there is a dispute about it) out of them. If one of the disks fails, will I be able to at least recover data from the healthy ones? If so, will I retain some sort of directory structure?
I'm targeting Linux + LVM as I write, but I'm opened to other spanned volume implementations. RAID is out of the way, because my disks have different sizes and speeds.
