Here's my new config. I ran pvcreate /dev/sda3 and created a Volume Group called VolGroup01 and a Logical Volume called LogVol00. I ran mke2fs /dev/drbd0 and was able to mount the filesystem. But it doesn't appear to be syncing with the other node. I'm not sure if it's because it's just not done with the initial sync or if I did something wrong. The output of cat /proc/drbd is below.

device /dev/drbd0;
disk /dev/VolGroup01/LogVol00;

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.
