Yes.

Yes, e.g. /dev/sda3

You never should mount the low level device (in your example /dev/sda3)
directly while the partition is under control of DRBD.
Instead do
    # mount /dev/nb0 /yourdirectory (e.g. /mnt/nb0)

Have a look on http://www.drbd.org and you will find a HOWTO, FAQ, articles
etc. It could be better understandable for newbies, that's true. As a newbie
you are the ideal person to find such parts in the documentation. Please
collect them and write down. Only a few words of improvement can save other
newbies hours in the future.
