I think this will change my configuration because I am planning on using LMV2. If my config looks something like this:
Perhaps something like:
on alice {
device /dev/drbd0;
disk /dev/vg_01/lv_r0;
...
When I run pvcreate do I use /dev/sda3 and create a volume group called vg_01. Or do I run pvcreate /dev/drbd0 (which isn't working right now).

Perhaps something like:
on alice {
device /dev/drbd0;
disk /dev/vg_01/lv_r0;
...
Would make more sense.
Anyone working w/ LVM will not be using the /dev/sd[x] or /dev/hd[x] obviously.
