I think drbd is working fine because when I force the primary (with 
--do-what-I-say) , I get this
/etc/init.d/drbd status
drbd driver loaded OK; device status:
version: 0.7.20 (api:79/proto:74)
SVN Revision: 2260 build by root at castor, 2006-07-26 13:30:03
 0: cs:Connected st:Primary/Secondary ld:Consistent
    ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0

but If I don't force it , nothing appen.

>> You said drbd is only starting on one node. I'm not sure if this will be helpful, but in my heartbeat/drbd environment, heartbeat does not actually start or stop drbd. Drbd starts as a normal system service. Heartbeat just manages it by issuing drbddisk commands to change drbd's state.
