crm_mon –i 2 #Overview Nodes/ Ressources with 2-sec-update cibadmin -E --force #Delete the complete HA-Configuration (resources) cibadmin -U -x /etc/ha.d/pen.xml #Update changes on HA-Config-File crm_resource -r resourcename -M -H target_host #Manual move of a resource crm_resource -r resourcename -C -H target_host #Delete status ob problems for a resource (unmanaged etc.)
Example:
crm_resource -r group_apache2 -M -H node1 #Move resource "group_apache2" to Node "node1"
To stop a resource temporary via cmd:
crm_resource --meta -r <resourcename> -p target_role -v stopped
To start a resource if heartbeat is running:
crm_resource --meta -r <resourcename> -p target_role -v started crm_resource --meta -r squid -p target_role -v started
To stop an unmanaged ressource/ clear ressource status:
crm_resource -r <resourcename> -C -H node
To delete a running ressource permanentely:
cibadmin -D -X '<primitive id="lbppdf_21"/>' cibadmin -D -X '<group id="lbppdf-cluster"/>'
