Re: [Linux-cluster] How to avoid two-nodes cluster split-brain withoutshared storage



Hi Barry Brimer,

Thanks your suggestion.
'tiebreaker ip', I searched the cluster documents, and only find the
definition of 'tiebreaker ip', but there is no description on how to
configure it.
Could you give some more detail about how to configure it.
