I've been struggling to set up an external HD managed using LVM. Everything looks just fine until I try to add the partitions to fstab.
But leaving details aside for a moment, I'm not finding any discussion anywhere about using LVM under Raspbian. I don't know if this is because it's trivial, or no one's doing it for reasons I just don't hear about.
So, could people please comment on this? Are you using LVM? Is it obvious why it should be a problem?
