The problem with this is that singular systems require a lot of engineering effort and produce interesting side effects when you attempt to make them reliable.

Any singular system is going to fail.

Ok, get two huge systems instead of a datacenter of small systems. You still have made great strides in reducing complexity.

and sharing state between them? or ensuring that only one is doing things when only one should be doing things? (STONITH needs to be implemented somehow)

the performance penalties you enjoy if you go down the shared disk path (which is still going to be a fun failure when it does fail)
