Nothing will work as long as these machines are diskless and inconsistent.

How do you want to set this up?  Is /dev/drbd0 going to be a PV?  It's not
clear from the rest of your message.

The DRBD device must be Primary on root1 before you can write to it.

What's using /dev/sda4 ?  "lsof | grep sda4" as root will tell you if you
can't see sda4 in the output from mount.  The first thing to do is to get sda4
umounted.  Then you can proceed with getting DRBD set up.
