[Linux-cluster] Clustered LVM for storage

Greetings,

I have an aoe device with a lot of storage in it that I would like to share
among four rhel 4 servers.  Each of the servers will mount it's own
storage, no data is shared between them.  e.g the servers won't be mounting
the same volumes.

I could create four different raid groups on the aoe device and present a
different one to each server, but that would waste space.
What I'd rather do is create one big raid group and use clustered lvm to
divvy the space between servers.

Is it possible?  Would it be enough to run just the clustered lvm daemon,
or would I need to install all of the cluster suite?
Are there other/better options?

Thanks!

Charles
