You can't really do this.

What you could do is have each node mount its disk on a different 
directory - possibly under /cluster/nodeX/ - then you'd have a whole 
mass of space available to all nodes.

The downside would be that each node would then be a single point of 
failure.

You could reduce the chances of failure by using pairs of nodes, setting 
up DRBD between pairs, then making failover CFS configurations.

Better have a lot of bandwidth between the nodes.
