<div dir="ltr" >Thanks for your reply. I'm using crmsh, are you refering to crm cluster add node command? It gives error on my cluster, when I'm trying to add ceha01 to a cluster by running crm cluster add ceha01. </div>

<div dir="ltr" >"ERROR: cluster.join: Abort: Cluster is currently active. Run this command on a node joining the cluster.<br>Connection to ceha01 closed."</div>

<div dir="ltr" >Can you explain how this command works in this case, otherwise do you have any other suggestions?</div>

<div dir="ltr" >BTW, </div>
<div dir="ltr" >1. Is there an issue updating cib.xml with cibadmin command when Pacemaker is running?</div>
<div dir="ltr" >2. Do you have idea where(which config file) crm_node command retrieves its data?</div>
