I would have 2 virtual IPs, one per 2-node cluster.
I would then have the servers in each location mount the virtual IP.
Should one cluster go down both IPs would migrate to the remaining
running cluster.
I think this would be a massive headache to configure in pacemaker but I
want to see if this scenario is even possible, and what problems it
could cause before I start looking into pacemaker.

I'm a new drdb user but as far as I can tell you'll need a cluster
filesystem like GFS or OCFS2 running on both nodes and then you "share"
with NFS. Note that that would still make it an active-standby solution
since the alias IP can only be on one of the two machines

Hello,
I am currently working on a highly available NFS service. I would
like to set this up with 2 servers, running RAID 6 and drbd running
on top of the raid device. I can then provide a virtual IP address
for the clients to mount the NFS directories.
This will later be expanded upon where we would need to write to the
NFS storage from another location. Is it possible to have 2 2 node
clusters, replicated by a stacked resource? Is the stacked resource
able to work in dual primary mode?
Here is what I want to setup.
[ Primary ]<-------------->[ Primary ]
[Primary]--->[Secondary] [Primary]--->[Secondary]
Is this possible?
