Ok, I think I got where the problem is. Before calling "monitor" or
"stop" it should check if the resource is stopped and if it is it
should return 0, not 1 as it does now when called not by root.
Right?
Not exactly. In case a prerequisite is missing (such as, say, the
pgctl program), the monitor and stop operations should not report
error but that the resource is stopped.
or fall back to some other method (such as grepping the process table)
The reason for all this
is that the RA should succeed on stop and return stopped (rc 7)
in case the software is not installed. That's common in case the
software is installed on a shared storage, but not on a clustered
filesystem. Or in case some nodes are never meant to run some
resource. See for example the apache or db2 or oracle resource
agents.
Thanks,
Dejan

/usr/sbin/ocf-tester can very quickly show whether everything
works as
it should ;-)
I can see an option to ocf-tester: --live <rsc_id>
Which would pull the resource data from the CIB (making sure it's
stopped & unmanaged) and would try to run it where the user
invoked the
command.
And then the GUI could call out to that script via a button.
Wouldn't that be nice.

Lars
