Hi, I don't have any test, but actually with the "crm status" you can see the status of all the cluster resources. So if one resource is failing you can see a set of "Failed actions" or, in the worst case, the resource is not anymore listed (so there is a issue with that resource). For additional commands and for managing the Corosync cluster look at https://docs.mirantis.com/openstack/fuel/fuel-7.0/operations.html Regards, Giuseppe On Tue, Jan 19, 2016 at 11:21 AM, Sean Murphy <murp at zhaw.ch> wrote: > Hi Guiseppe, > > That's great - thanks for that. > > On a very related note, do you have some set of reasonable tests that you > run on > a HA system to determine if it is behaving itself?
