[blfs-support] A Basic Question about LVM

[Rob]

Do all disks need to be empty before creating an LVM structure?
I have 9 disks, 5 of which are loaded with data. I'd like to combine
them all together to make one array, being able to expand as needed.
But before I do, should I empty all the disks first?

I don't use LVM or a regular basis, but it's apparent to me that
creating physical and logical LVM structures requires changing the
partitions on the drives. In that case everything gets reformatted.

The commands may complain about existing partitions, so you may need to
redo the partition tables on the drives before using LVM.

You might want to consider btrfs in lieu of LVM.
