[Linux-cluster] Combining LVS and RHCS

Assume I have set up an LVS 'blob' that has two LVS routers and some
number of real servers used to load balance services.  Assume I have
also set up a third tier using 2 servers and RHCS to cluster shared
storage arrays.

- From the reading I have been doing, a cluster requires quorum to
continue to function so a two-node cluster providing the shared storage
would seem to fail to meet quorum if one of the two servers dies.

Can the servers in the second-tier of the LVS blob that are providing
load balanced services also have RHCS components installed on them and
just not be part of any service specific failover domains?  This way the
total number of member servers in the cluster would still be greater
than half, even if one of the two storage server nodes failed.

Thanks
