Problem synchronization DRBD after restart Servers

[PveUuser]

Hello
I installed 2 servers Proxmox ve 3.4, after setting up the DRBD Service, the synchronization works very well.
but when i shutdown both servers the synchronization doesn't work anymore and the same problem recurs when i keep starting the Servers 2 days, what can I do?

Have a look at the wiki

http://pve.proxmox.com/wiki/DRBD9

and the "post-up drbdadm adjust all" part in particular, maybe can solve
