Creo que he encontrado la solución a mi problema...Ahora al bootear se ponen bien como primary/primary, encontré esto e una página:
Dejo el enlace:
http://realtechtalk.com/DRBD_WFConnection_ProblemSolution-1042-articles
Básicamente explica que a veces el cortafuegos de iptables que viene configurado por defecto bloquea el tráfico drbd pero yo el iptables lo tenia off y el selinux en disabled.
He hecho lo que viene abajo y he añadido algo que no viene ahí que me daba error al ejecutarlo directamente:
En ambos nodos:
drbdadm detach r0 drbdadm attach r0
drbdadm disconnect r0 drbdadm connect r0
En ambos nodos tambien, porque es activo/activo ejecutamos:
drbdsetup /dev/drbd0 primary -o
Ahora al reiniciar sincroniza bien y se quedan siempre como primary/primary
