You could use this:

# echo 1 > /proc/sys/vm/block_dump

then every read and write operation on block devices shows up in dmesg
with the PID, process name and the block id. (This can be a lot of
lines, so dmesg -c might be useful) I'm not exactly sure how to identify
which files belong to which block, though.
