You could have left space unused and create two partitions after OS 
install. One for the metadata and the other for /dev/drbd0
( why not just start with drbd0? )

You might want to change this to an external meta-disk /dev/sda8.

If you meant to use the space /var is on now, nothing has to change. 
Make sure to umount /var and check your fstab (even reboot).
After that create a new filesystem on /dev/drbd0 when it's brought up 
and primary.

But if /var is already in use with typical /var content then boot in 
single-user mode and move everything to a /var directory on your root 
disk /.
