The worst case would probably involve reading/writing the same file extents across multiple nodes. You could probably whip up a script using /bin/dd for such a thing. Or is that too evil for you?

I am looking for IOR scripts that represent pathological use cases for file systems. Something like shared file access with a small, unaligned block size or random I/O to a shared file. Does anyone has some input for me there that he/she is willing to share?
