What do you mean with "inconsistency" here?

Yes, you can.
With drbd 0.6.X with the restriction that it should not change the
logical block size too often (best: not at all).
The drbd is basically just an other block device.

If what you find at drbd.org is not enough, I don't know.

Maybe there are some documents out there which are not yet linked
at drbd.org. Someone?

Best you move both to secondary state while they are still
connected, then shut down the network and everything else.

Probably you have to tweak a little bit the order of your
init.d/*/* resource scripts.
