So the problem occurs even with consistent file handles?  Hmmm...

* Does the partial file exist in the cluster fileystem when the "stale
  file handle" message is printed?

* Is the filesystem mounted after the failover?  Can you use "ls" to
  list a directory on the client?

* What happens if you disable a node with "ctdb disable"?  Do you get a
  clean failover?

Thanks...

peace & happiness,
