This message concerning clone-max still appears once per minute in syslog, although both nodes are in standby for days and the drbd resource is unmanaged too.
With stat i checked that the RA is called once per minute. With strace i found out that it is lrmd which calls the RA with the option "monitor".
But why is it still checking ? I thought "standby" for the nodes means the cluster does not care anymore about the resources. And "unmanaged" means the same for a dedicated resource.
So this should mean doubled "don't care anymore about drbd".

What is interesting: Although saying "action monitor not advertised in meta-data, it may not be supported by the RA", it is:

/usr/lib/ocf/resource.d/linbit/drbd:

 ...
case $__OCF_ACTION in
start)
        drbd_start
        ;;
 ...

monitor)   
^^^^^^^
        drbd_monitor
        ;;
 ...

And the in the "crm ra info ocf:linbit:drbd" mentioned "monitor_Slave" and "monitor_Master" i can't find in the RA. Strange.
Doesn't "crm ra info ocf:linbit:drbd" retrieve its information from the RA ?

In the RA i just find:
<actions>
 ...
<action name="monitor" depth="0"  timeout="20" interval="20" role="Slave" />
<action name="monitor" depth="0"  timeout="20" interval="10" role="Master" />
 ...
</actions>

This is what "crm ra info ocf:linbit:drbd" says:
 ...
Operations' defaults (advisory minimum):


     ...
    monitor_Slave timeout=20 interval=20
    monitor_Master timeout=20 interval=10
