[Pacemaker] DRBD primary/primary + Pacemaker goes into split brain after crm node standby/online

Hi Everybody,

I have an issue with a 2-node Debian Wheezy primary/primary DRBD
Pacemaker/Corosync configuration.

After a 'crm node standby' then a 'crm node online', the DRBD volume
stays in a 'split brain state' (cs:StandAlone ro:Primary/Unknown).

A soft or hard reboot of one node gets rid of the split brain and/or
doesn't create one.

I have followed http://www.drbd.org/users-guide-8.3/ and keep my tests
as simple as possible (no activity and no filesystem on the DRBD volume).

I don't see what I am doing wrong. Could anybody help me with this please.

Regards,

Alexis.
