I've got a homebrew Linux high-availability cluster here, running Linux-HA
and DRBD. Basically, it's a simple failover situation, with one primary node
and one secondary node that switches to primary when the original node fails.

The cluster has a shared IP assigned to it, and some disk space that is kept
in sync between the two machines (and is only available on the current primary).

In order to back up this shared disk space, I thought I'd set up three
clients: NodeA, NodeB, and SharedIP (all DNS names that resolve to different
IPs, though currently NodeA and SharedIP are both the same physical
machine). The NodeA and NodeB clients have save sets of "everything but the
shared space" and SharedIP only backs up the shared space.

However, Networker is outsmarting me, and listing the shared disk space as
belonging to NodeA, not SharedIP.

Is there a way to do what I want? (keep all backups of the shared disk
associated with the SharedIP client)
