Hi.
I'm very new to drbd. In fact, I'm still testing it.
I'm using openSuse 13.2. I could configure drbd in both machines and seems to be working well but ...
The problem occurs when I try to reboot the 'primary' machine - the one that have the primary or active file system. It cannot simply boot.
It can boot if a take the device out from /etc/fstab and mount it after boot:
UUID=9585d7b4-fac5-4f19-aea3-95debdf86481 swap swap defaults 0 0
UUID=9c052c13-c838-4488-959f-c0d5ef16377d / xfs defaults 1 1
UUID=2dc37455-631e-48da-a308-990d2b6a404c /boot ext4 acl,user_xattr 1 2
#/dev/drbd0 /dados ext4 acl,user_xattr,usrquota,grpquota 0 0
I also tried to make sort of 'manual mount' after boot using /etc/rc.d/after.local, using the mount command:
mount -o acl,user_xattr,usrquota,grpquota /dev/drbd0 /dados
but even so I could not boot because the device drbd0 seems to be very lazy if I interpreted correctly this peace of log:

I could circunvent this behaviour configuring systemd in order to only execute the script /etc/rc.d/after.local after drbd initialization but I think that the mount should be executed from /etc/fstab code as usual in linux systems.
Can anyone give me some help?
Thanks.
Ricardo
