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

Reported by: Daniel Kahn Gillmor Owned by: Jamie McClelland

Sensitive: no


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.
