Hi,
I have a cluster (2 machines) email using the pacemaker / corosync as
Active / Passive.
Already configured filesystem (, ocf: heartbeat: Filesystem) SFEX, ping

one group.

Dear all
Attached is my 2-nodes, master slave cluster configuration with master-slave

I've modified pgsql resource agent to log its "main" entry with the

My problem is that while the single node is running, the m

There is also ways to get tons of trace logging without recompiling:

Are you using cman (cluster.conf) or the corosync plugin (corosync.conf)
Pacemaker only starts corosync if cman (which is a particular way of running
corosync) is being used.
Hi Lars,
that's why I wrote: The interested reader of that list does
now know why I tried crm_simulate... :-)

Hi Lars,
no you're not missing something.
I just intermixed two acceptable solutions and
the way I asked for it.
So, for letting the resources stay where they are,
you're absolutly right.

Hi Andreas,
You are right and I am blind, the fail-over work now when the network

Hi!
I had to add additional logging to sources and build a custom version to
figure out what is the problem.
It turned out that on the problem node root user had GID not 0 but 501.
Very odd. :-)
