Hi, Cristiano
      pacemaker only get the cluster name from corosync on the first initialize. Then it will store the name in cib.
even you change the culster name in corosync.conf, pacemaker will not update it.

HI Zhen & Ulrich

I have tried to duplicate the issue but I wasn't able to reproduce.

Corosync is updated all the time

So I will not open any bug for the moment.

I'm sorry for the wrong heads up!

What is sure is that crm resource show do not reflect dinamically the cluster name.

It is written ONLY during ha-cluster-init.

If you change the cluster name while cluster is initialized you have to change it manually with crm configure edit

Is this working as designed?

Thanks,

Cristiano

Hi Cristiano,

Thanks for your report. I suggest you file a bug for this at https://bugzilla.suse.com so that it can be routed to the right person quickly.

It's probably a bug to fix, I think, so don't mix yast and HA bootstrap scripts to setup your cluster ATM:)
