Create a swap lv in the vg you created out of /dev/md1, assuming /dev/md0 is /boot.

I am mirroring two drives during install, what's the best practice here for the swap partition? Maybe two separate lv's from independent vg's *not* mirrored for swap and the let the OS manage it? Boot and the / vg will be mirrored.
Thanks! jlc

Oh, I thought it wasn’t good to run swap inside software raid? If I was wrong, I assume this is beneficial since if one of the HD’s tanks while its running, it will survive the failure and not need to reboot?

That is an old assumption from the infancy of software raid, less than optimal installed ram, and slower processors. When ram was expensive, you used more swap because it was cheaper. But ram is so much cheaper now that it make no sense to run a machine that needs to touch swap except in an emergency.
