A different approach is to add a file in the root fs for swap instead
of adding a dedicated partition / logical volume.
The performance will be somewhat lower than from a partition / lv, but
it is much simpler and less risky to add.
You can also use the pri=<priority> option in fstab so that the swap
partition is used first, and only if that becomes full the
swap file is used.
