align all disk accesses for MF/PL servers to 4MiB

Description

MF/PL uses a stacked set of tools for disk access. We should make sure that every piece of the toolkit on every server is aligned to 4MiB boundaries. This should reduce overall kernel activity for each disk write and read.

I've started a page describing all the various parts and how to ensure they're aligned.

Probably a good first step would be to write a script that checks each subsystem and flags non-aligned layers.
