question about LVM

i have a really quick question about LVM, been trying to search but can't really find the answer

here's the scenario
i have my new quad core phenom system running arch, with an LVM volume on a few 1TB drives. i was overclocking it the other night and running geekbench, pulled 8300 flat anyway, not too bad since i started at 4900 on the arch kernel, and then hit 6800 with a custom zen patched kernel. anyhow, before i get carried away, what i want to do, is slap a spare drive and install windows 7 for a wider suite of benchmarks. but i'm worried that the drives with the lvm volume may not go in the same order when i pull the windows drive out.

so what i want to know, is does the order of the drives with the lvm volume matter, or does LVM not care about the order at all?

Re: question about LVM

It shouldn't care. LVM uses its own identifiers/uuids.

Re: question about LVM

Correct - if you look at /etc/lvm/lvm2.conf it should show that it just does a scan within /dev to find the PV's that it needs.

Re: question about LVM

i was pretty sure thats how it worked....but pretty sure just isn't enough sometimes. like when you're looking at 3TB's of data
