We query the location of a resource in bash with this:

if [ ! "$(/usr/sbin/crm_resource -Q -r resourcename -W)" = "$(hostname)" ];
then

just have a look at "man crm_resource" i'm pretty sure you'll find
something suitable.

"crm resource status <resourcename>" is also possible. But having some
more script-friendly output would be good.

Hi,

I also tried with 'crm_resource'.
I'm not a python export, but I inserted this line:

if os.system("crm_resource -r " + myVM + " -W | grep 'is running'") == 0:

which works !

thanks to the list.
