There is/are local filesystem loopback FS(s). I don't renember the name of 
the one I know. Just search the archive of the ML.
The error probabilities could be added quite easily, I think.
Just add something something like:

if (throwdice(path))
	return -EIO;

in the apopriate functions. 
You need of course an hash of filenames with the probabilities build out of 
the errorfs.conf and a 'throwdice' function.

Best,
