1. Where our single ext4 file server is predictable under load (it just
gets slower), with both nodes up, why does the cluster fail so badly
under ext4 but absolutely screams under ocfs2? The strange thing is that
the clustered ext4 actually performs better when only one node is up.

ext4 cannot be concurrently mounted on multiple nodes.

Other setups use it:

It is failover cluster where filesystem is always mounted by a single
node at a time. What made you think it is used as cluster filesystem?
