Finally, if you really do need to use sanlock, I'd create some

to configure libvirt to do this (but I know it's possible because
RHEV/ovirt uses sanlock and libvirt in this way.)

Thanks! I figured this seemed like my only option, and we have the means
of doing it. I just don't know how to configure it properly within
Sanlock and cannot find documentation on doing this.
This man page (
https://fedorahosted.org/sanlock/) appears to show
utilizing LVs from shared storage, but it's not very clear why you need
two LUNs (or if you even need two for a 2 node setup), why it has to use
the "direct init" command, if you have to manually add leases now
instead of using the auto lease feature if you're using that, etc. One
of the things I liked about using Sanlock on NFS is the auto lease
creation feature.
Anywhere you can think of to point me towards more information on going
down this route with a 2 node setup?
