Hi,
i got a 2 Node Cluster up and running and right know i am trying to
configure a Nagios3 Resource. Therefore i already fixed the nagios init
script as it dind't pass the LSB Compatibility Checks as described here:
http://www.clusterlabs.org/doc/en-US/Pacemaker/1.0/html/Pacemaker_Explai
ned/ap-lsb.html
I just needed to make sure the pid file gets removed if the stop
function is called. After this small change i passed all the LSB Checks.
Below you find the error message:
root at pilot01-node2:/var/run/nagios3# crm_verify -LV
crm_verify[7094]: 2010/06/23_16:37:27 ERROR: unpack_rsc_op: Hard error -
res_Nagios_monitor_0 failed with rc=6: Preventing res_Nagios from
re-starting anywhere in the cluster
crm_verify[7094]: 2010/06/23_16:37:27 WARN: native_color: Resource
res_Nagios cannot run anywhere
Warnings found during check: config may not be valid
I tried to find out what the init scripts must provide for allowing it
to use it in pacemaker but i just found the LSB Compatib. Hints on the
pacemaker website. I think i configured the primitive wrong or maybe the
init script is still wrong? Even if i configure it with a op monitor
action it fails. And even a crm resource cleanup res_Nagios doesn't
help me starting the resource.
I can run Nagios manually on the active node. I linked all shared
directories to my cluster storage device like this:
