Judging by your pvcreate statement, it appears that you are trying to
run lvm2 on top of a drbd device. In that case, I believe /dev/drbd0
needs to be primary before you can run pvcreate. You can put /dev/drbd0
in primary because drbd is not starting correctly.
What device is /dev/drbd/r0? Most block devices in RHEL are going to be
/dev/sd[a-d] (SCSI or SATA) or /dev/hd[a-d] (IDE).
