[Pacemaker] A secondary DRBD is not brought online after "crm resource online" in Ubuntu 14.04

Hello.
Ubuntu 14.04, corosync 2.3.3, pacemaker 1.1.10. The cluster consists of 2
nodes (node1 and node2), when I run "crm node standby node2" and then, in a
minute, "crm node online node2", DRBD secondary on node2 does not start.
Logs say that "drbdadm -c /etc/drbd.conf check-resize vlv" fails with an
error message: "No valid meta data found" on the onlining node. And,
surprisingly, after I run "service drbd start" on node2 manually,
everything becomes fine.
Maybe something is broken in /usr/lib/ocf/resource.d/linbit/drbd, why
cannot it start DRBD? Or I am misconfigured somehow? Could you please give
an advice what to do?
I have the following configuration (drbd + mount + postgresql, but
postgresql is innocent here, so just ignore it):
*root at node2:/var/log#* crm configure show
node $id="1017525950" node2 attributes standby="off"
node $id="1760315215" node1
primitive drbd ocf:linbit:drbd \
params drbd_resource="vlv" \
op start interval="0" timeout="240" \
op stop interval="0" timeout="120"
primitive fs ocf:heartbeat:Filesystem \
params device="/dev/drbd0" directory="/var/lib/vlv.drbd/root"
options="noatime,nodiratime" fstype="xfs" \
op start interval="0" timeout="300" \
op stop interval="0" timeout="300"
primitive postgresql lsb:postgresql \
op monitor interval="4" timeout="60" \
op start interval="0" timeout="60" \
op stop interval="0" timeout="60"
group pgserver fs postgresql
ms ms_drbd drbd \

property $id="cib-bootstrap-options" dc-version="1.1.10-42f2063"

stonith-enabled="false" no-quorum-policy="ignore"
last-lrm-refresh="1420304078"
rsc_defaults $id="rsc-options" \
resource-stickiness="100"
The cluster and DRBD statuses on node2 look healthy:
*root at node2:/var/log#* crm status
...
Online: [ node1 node2 ]
Master/Slave Set: ms_drbd [drbd]
Masters: [ node1 ]
Slaves: [ node2 ]
Resource Group: pgserver
fs (ocf::heartbeat:Filesystem): Started node1
postgresql (lsb:postgresql): Started node1
*root at node2:/var/log#* cat /proc/drbd
version: 8.4.3 (api:1/proto:86-101)
srcversion: F97798065516C94BE0F27DC
0: cs:Connected ro:Secondary/Primary ds:Diskless/UpToDate C r-----
ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0
Now I switch node2 to standby and verify that DRBD on it has really shot
down:
*root at node1:/etc/rc2.d#* crm node standby node2
*root at node2:/var/log#* cat /proc/drbd
version: 8.4.3 (api:1/proto:86-101)
srcversion: F97798065516C94BE0F27DC
*root at node2:/var/log#*
Then I switch node2 back online and see that DRBD has not been initialized
and reattached again!
*root at node2:/var/log#* >syslog
*root at node1:/etc#* crm node online node2
*root at node2:/var/log#* crm status
...

Master/Slave Set: ms_drbd [drbd]
