yum install drbd-pacemaker returns:
                                        Package drbd-pacemaker-8.3.7-2.fc13.x86_64 already installed and latest version
also drbdadm says:

Ok, i replaced with drbd1 which is my device and got on var/log/messages:

crmd: [28175]: ERROR: process_lrm_event: Op dlm:1_start_0 (call=10): Cancelled
crmd: [28175]: ERROR: do_lrm_invoke: Not creating resource for a delete event: (null)

And my system broadcast a message of kernel bug:

Don't know your DRBD version, but make sure you've got the
corresponding udev stuff installed.   If not, replace references to
/dev/drbd/by-res/* with their actual device nodes (/dev/drbd0, for
example)
