crm configure show remote-db8-ca-3a-69-60-f4
node remote-db8-ca-3a-69-60-f4:remote \
        attributes OpenStack-role=compute standby=off
primitive remote-db8-ca-3a-69-60-f4 ocf:pacemaker:remote \
        params reconnect_interval=60s server=db8-ca-3a-69-60-f4.ipa.pthl.hk

        op start interval=0 timeout=60s \
        op stop interval=0 timeout=60s \
