I'm not sure my fix is correct.
According to
https://github.com/ClusterLabs/resource-agents/commit/96ff8e9ad3d4beca7e063beef156f3b838a798e1#heartbeat/VirtualDomain
this is a regression which was introduced in April '11.
So the fix should be the other way around: Introduce a parameter that

Hi Dejan,
this way, the cluster never learns that it can't start a resource on
that node.
I don't consider this a solution.

I don't think you are. Some non-root pratically being able to remove any
file is certainly a valid concern.
Thing is: I needed an RA that configured a cronjob. Florian suggested
writing "the" symlink RA instead, that could manage symlink. Apparently
there was an IRC discussio

The reason was that libglue2 and cluster-glue were not installed from
the clusterlabs repository, as the rest of the packages were, but
instead they were pulled from the original opensuse repository in an
older version.

Hi
as some of you might have seen on the pacemaker list, I tried to install
a 3 node cluster and there were ipc issues reported by the cib and
therefore the cluster could not start correctly.
The reason was that libglue2 and cluster-glue were not installed from
the clusterlabs repository, as the

weeks ago. I used the last version from thread "New stateful RA:

Jon and I just talked on IRC and my misunderstanding was that he
intended to _start_ conntrackd via an init script and have the cluster
only do the cache commiting/flushing and monitoring work.

the probe. Within that function, crm_master is called and sets an
appropriate promotion score. That keeps the master instance running in
its current location.

OCF resource agents should be able to run meta-data, monitor, and
stop even when there is no required software installed:
- meta-data should run ok
- monitor should return 7 (resource stopped)
- stop should return 0 (success)
