if it's enough to find out "after" the fact - meaning, when there
already IS excessive disk IO, then iotop is the very best thing since
sliced bread.
imho even better than top :)

Can  you also give
https://bitbucket.org/darkfader/black-magic/src/d14a84157990/usr/local/bin/blksched
a test run in this situation and let me know if it helps for you?
