Hi

Config pacemaker on centos 6.5

I have my own resource file and I start stop the proxy service outside of pacemaker!

I had an interesting problem, where I did a vmware update on the linux box, which interrupted network activity.

Part of my monitor function on my script is to 1) test if the proxy process is running, 2) get a status page from the proxy and confirm it is 200


This is what I got in /var/log/messages

And it stay this way for the next 12 hours, until I got on.

I poked around and to fix it I ran this
        /usr/sbin/pcs resource cleanup ybrpip
        /usr/sbin/pcs resource cleanup ybrpstat

Bascially I cleaned up the errors and off it went all by itself.

So my question is how do I configure it or what do I need to change in the resource script file to send a temp error back to pacemaker so that it should have kept trying to check the status of proxy ?

It seems to me it tried once and then failed... although the log says filed after 1000000 failures ....  how can I change that to infinite and where is the interval setting for this, cause in the config above it looks to me like it should be infinite ?


Thanks
Alex
