I am confused between the official docs on http://drbd.linbit.com/docs/about/ and some drbd tutorials on ubuntu wiki concerning the step "Preparing your lower-level storage". Should we partition the storage and format it? Looks like we shouldn't format it, to avoid "create-md exit code 40, drbd will take care of that. Then should we mount it on both devices? I am suspecting most errors at this stage of preparing the storage.
