[Linux-cluster] How can I re-assign cluster id

[Pedro Gonzalez Zamora]

Dear Christine

I have set <cman cluster_id="1470"/> and I trying again but I get this
error:

cman: unable to set cluster_id

Could you tell me please more about cluster name hash, how it works and how
can I change the values?

Best Regards
