@Stefan, thanks for the reply. It seems my information was not that

The problem is with the pacemaker drbd agent:

Here a snippet of this agent:

Ah yes, that helps a lot. So somehow (not sure this is because I am
using the Linux Cluster Management Console for setting up my test
environment or because timing is just in my favour) I seem to avoid this
because the drbd init script already loads the module. So by the time

@Jacob, sorry for the long delay. I tried to confirm your report but

/etc/init.d/drbd. That could indeed be wrong on start. Though the values

I had the same problem and found out that there is a different behaviour
of the drbd agent between just stop and start the drbd resource or
rebooting the system. When you stop drbd, the drbd module stay loaded so
when you start drbd again, the validity check of the agent correctly
detects an 8.3

I still have problems after upgrading to drbd8-utils
2:8.4.3-0ubuntu0.12.04.2~rc4.
Especially the pacemaker drbd agent does not work
(/usr/lib/ocf/resource.d/linbit/drbd). For example, there is a line
do_drbdadm $DRBD_TO_PEER -v adjust $DRBD_RESOURCE which translates to
drbdadm -c /etc/drbd.conf
I can confirm that drbd8-utils 2:8.4.3-0ubuntu0.12.04.2~rc4 works fine,
at least for me.
I put one node to standby, installed drbd8-utils
2:8.4.3-0ubuntu0.12.04.2~rc4, did not change drbd.conf, brought node up
again and migrated all resources to that node. Everything is working as
expected:
@Thilo,
this is odd. Locally I see the same adjust command but it will get
translated into a drbdadm-83 call which works. Would it be possible for
you to create '/tmp/drbd.ocf.ra.debug', set it to chmod 700 for root and
touch /tmp/drbd.ocf.ra.debug/log as root. Then service corosync

Thilo, I looked at the debug data you sent me and somehow it seems that
using hearbeat runs a different resource agent. So drbd itself ships a
resource agent in /usr/lib/ocf/resource.d/linbit/drbd but hearbeat uses
another one (.../resource.d/heartbeat/drbd) that comes with a different
package
Must admit the two scripts as they are installed on my test system
differ more. Weirdly in your output there was a version check of
++ DRBDADM_VERSION_CODE=0x08030b
++ DRBDADM_VERSION=8.3.11
+ (( 0x08030b = 0x080302 ))
and that check I cannot find in the heartbeat/drbd script. And the
That really depends on the Pacemaker configuration. If the primitive
DRBD resource uses ocf::heartbeat::drbd, it's the resource agent from

Thanks, Martin, fot the clarification. The ocf::linbit::drbd agent is

I'm not sure if anyone has mentioned it yet, but the command syntax to
the drbdsetup command has changed totally between drbd8-utils 8.3 and
8.4
e.g. if you are using drbd-utils 8.3 then the command is
drbdsetup /dev/drbd0 show
if you are using drbd-utils 8.4 then the command is
drbdsetup show
Hmm, just to clarify: when using the drbd8-utils 8.4 package and the
kernel module 8.3, then drbdsetup execs the drbdsetup-83 compatibility
module which implements the old syntax, and will also if necessary swap
the first two arguments for forward compatibility

This was done because later point releases of 12.04 come with newer

@Numérigraphe,
thanks for the quick testing. To answer the question from #12 first: The
