<div dir="ltr" >Thank you for your suggestion. The case I have is, I have host1 and host2 in cluster that has resources running, then I try to join host3 to the cluster by running "crm cluster join -c host1 -y". But I get this "Configuring csync2...ERROR: cluster.join: Can't invoke crm cluster init init csync2_remote on host3" issue. Are there any other requirements for running this command?</div>

<div dir="ltr" >Thanks</div>
