Can you help me with a sample ? I was reading through the docs and tried
some samples but couldn't get it working.
Do I have to set some environment variables that point to the resource
before calling crm_master ?
Here is a part of the cibadmin -Q that represents such a master / slave
resource, maybe you can give me the command for the sample resource
LX-AUDI01-drbd
