Which hypervisor is this? KVM? If so, please post the agent logs. I don't have much experience with DRBD, but CloudStack doesn't really care about the underlying storage implementation. It (rather the hypervisor) cares about the protocol (NFS/ISCSI/FC). If the hypervisor is unable to mount the primary storage, then there's not much CloudStack can do.
