[Pacemaker] ClusterMon - using 'crm resource failcount ...' in external agent

[D.Gossrau]

Hi,

I'm trying to get the failcount of a resource (crm resource failcount 
<rsc> show <node>) in a script which is used in ClusterMon as external 
agent. The configuration is as follows:

# resource Cluster Monitor
primitive resClusterMon ocf:pacemaker:ClusterMon \
     params user="root" \
     extra_options="-fn --external-agent=/tmp/test.sh" \
     pidfile="/var/run/clusterMon.pid" \
     htmlfile="/usr/share/tomcat/webapps/andphone/ClusterStatus.html"


shell script /tmp/test.sh:
#!/bin/bash
LOGFILE="/var/log/clusterChange.log"
echo "${DATE} ($$): ${CRM_notify_node}, ${CRM_notify_rsc},
${CRM_notify_task}, ${CRM_notify_desc}, ${CRM_notify_rc}" >> ${LOGFILE}

/usr/sbin/crm resource failcount ${CRM_notify_rsc} show 
${CRM_notify_node} >> ${LOGFILE} 2>&1

exit


Following error occurs:

Traceback (most recent call last):
   File "/usr/sbin/crm", line 33, in <module>
     from crm import main

     return p.wait(timeout=timeout)
   File "/usr/lib64/python2.6/subprocess.py", line 1296, in wait
     pid, sts = _eintr_retry_call(os.waitpid, self.pid, 0)
   File "/usr/lib64/python2.6/subprocess.py", line 462, in _eintr_retry_call
     return func(*args)
OSError: [Errno 10] No child processes


If I call the script test.sh manually after setting the used environment 
variables (CRM_notify_*) the failcounts are displayed correctly.

Is there something wrong in my enironment ? Could somebody enlighten me ?

My environment :

Scientific Linux 6.3
pacemaker-cluster-libs-1.1.7-6.el6.x86_64
pacemaker-cli-1.1.7-6.el6.x86_64
pacemaker-libs-1.1.7-6.el6.x86_64

corosync-1.4.1-7.el6.x86_64
resource-agents-3.9.2-12.el6.x86_64

Thanks for any hints !

Kind regards,
