===Heartbeat Cluster operations===<br />
<br />
* check cluster status<br />
crm_mon -1 -r<br />
<br />
* Migrate Resource group to specific node without creating constraint<br />
crm_resource -M -f -Q -r rg0 -H c20.chepkov.lan<br />
<br />
Wait until resource will be migrated, then<br />
<br />
crm_resource -U -r rg0<br />
<br />
* Mark resource unmanageable by cluster<br />
crm_resource -p is_managed -r apache_svn -t primitive -v off<br />
<br />
* Stop resource<br />
crm_resource --meta -r rg0 -p target_role -v stopped<br />
<br />
* Remove stopped role<br />
crm_resource --meta -r rg0 -d target_role</div>
