And you could have set your laptop on top of a tape degausser. You have
been making regular backups haven't you?
I had a backup a week old, but that doesn't excuse LVM from *escalating
a lost sector into a lost filesystem*. Why ask me about my personal
disaster recovery when we talk about taking action to minimize the
chance of disaster for the whole class of storage?
When LVM is inflicted on to situations that cannot benefit from it, the
end result is you made something more fragile for no gain: that can't be
right.
