[DRBD-user] ERROR: meta parameter misconfigured, expected clone-max -le 2, but found unset

[Gionatan Danti]

Hi list,
I have troubling configuring Pacemake to correctly manage a DRBD 
resource. The basic problem is that resource does not start, emitting 
the following error:

ERROR: meta parameter misconfigured, expected clone-max -le 2, but found 
unset

So it seems the OCF script I can found in 
/usr/lib/ocf/resource.d/linbit/drbd does not find metadata it expects in 
the resource definition. However, metadata *are* specified in the 
resource file.

Any suggestions on how to fix the problem?

System info:
- CentOS 7.4 x86_64
- DRBD package kmod-drbd84-8.4.10-1_2.el7_4.elrepo.x86_64
- DRBD utils drbd84-utils-9.1.0-1.el7.elrepo.x86_64

Command line used to create the resource (I also tried with PCSD WebUI, 
with no difference at all):

[root at blackhole cluster]# pcs resource create drbd_vol1 ocf:linbit:drbd 
drbd_resource=vol1 op monitor interval=5s timeout=30s role="Slave" 
monitor interval=15s timeout=30s role="Master"
[root at blackhole cluster]# pcs resource master drbd_vol1 master-max=1 
master-node-max=1 clone-max=2 clone-node-max=1

Cluster and resource definition file /var/lib/pacemaker/cib/cib.xml 
(trimmed):

...

         <primitive class="ocf" id="drbd_vol1" provider="linbit"

         </meta_attributes>
       </master>
...

Thanks you all.
