[SOLVED] LVM works, but not at boot

I am trying to set up a hard drive with lvm, only one hard drive is in the volume group atm, I'm planning on extending it as soon as I can get it to work.

I can access the volumes fine if I run arch from a separate hard drive, everything works, and /boot is in its own primary partition. But when I try to boot from it it gives me device does not exist. I enabled the lvm hook, I can see /dev/mapper/hdgroup0-volroot in busybox, but I can't mount it.

Any ideas?

Do you have the correct "root=" line in your bootloader's kernel line? Is it in fstab?

Perhaps try with rootdelay=5 as well?

Yes I have root=/dev/mapper/hdgroup0-volroot, and its in fstab (not that fstab is even being read)

root delay wouldn't help at all because after it drops me to a busybox shell I can't do a manual mount.

USELVM = "yes" in rc.conf?

Rebuilding my initrd fixed it.
