We do have the right kernel support for our didsks. But, you do not need
a lot of CPU activity to generate noise. Just enough to disrupt the

kupdated - journal update
kswapd - swapper
bdflush - flush IO
All/any of them could cause problems fir what you are doing, but I don't think
LVM is your problem.
