Andrew, Thanks for your help!
Please find the core files attached (3 from about 100).
pcs status
...
Version: 1.1.8-7.el6-394e906
Installed:
corosync.x86_64
0:1.4.1-15.el6_4.1
pacemaker.x86_64 0:1.1.8-7.el6
cman.x86_64
0:3.0.12.1-49.el6
Problematic configuration:
pcs resource create
ClusterMonScript1 ocf:pacemaker:ClusterMon params user="root"
update="1" extra_options="-E /usr/local/bin/example.sh -e
127.0.0.1"
Regarding to my problem: is it possible in Pacemaker to run one command and get the status of the node in the one value?
We do not want to parse the output of the command "pcs status".
Like
pcs status node node_name that will return online or offline (or standby).
Thank you for your help!
Best regards,
Michael
