[CentOS] Determine high i/o reads/write directories

I have a DRBL server, basically an nfs fileserver, which I am
rebuilding. I want to put the high i/o directories on a separate raid
array for performance. Currently everything is under / in one raid
array.

How can I tell which directories, obviously other than /home, are
getting high reads and/or writes? Any tools to measure i/o per
directory?

Thanks
