My machine was running the whole time I was rearranging things, except for the few minutes it took to physically swap disks (hot swap doesn't work). The logical volumes I was moving around were *in use* while I was moving them. That's why I do it that way. If your hardware does hot swap, there's no need to stop *anything* if you use my system. The only catch is that you should use explicit FSIDs when exporting, to avoid the "stale nfs handle" when you reboot, but this is a feature of LVM, not raid.
