When I booted the box after this, I got a kernel panic, the typical "Can't find root device".
Reading https://fedoraproject.org/wiki/How_to_debug_Dracut_problems , I did the following:
# lvm vgscan # lvm vgchange -ay
And then
# ln -s /dev/mapper/<volumegroup>-<root_volume> /dev/root # exit
After this, the box boots up normally, and everything works as it should. However, when I reboot, it again fails to find the root device.
So, after all this, my question is, how do I make Dracut (I'm assuming) understand that this LVM volume is my root device and pick it up automatically?
What does your kernel line in grub look like?
