You need to give a lot more detail on that, try having a quick read of:

	http://www.catb.org/~esr/faqs/smart-questions.html#beprecise

Basically there are all sorts of possible problems from kernel bugs, node 
hardware problems through to various network problems...

Useful information would be things like:

	/etc/fstab from the nodes
	output of the mount command
	the output of strace when you try and do the 'cp':

		strace -o cp.log -e trace=file cp /path/to/file /path/to/destination

good luck!
