And the thing I love about Linux is that you have total control. You want to turn off swapping? swapoff -a. There it is, gone, and the system is still mabulating away happily. Delete the old swap partition? lvremove /dev/mainvg/swaplv. Create the new swap partition? lvcreate -i 2 -I 64 -L 4G -n swaplv mainvg to create a 4GB partition striped across the two disks. After a bit of mental prodding I remembered I have to do mkswap /dev/mainvg/swaplv to make the partition look like a swap device, and then swapon -a Just Works. There you go, 4GB of new improved faster swap space. No reboots, no special utilities, no "what's this C:\win386.swp file?". Easy.
