We had setup opennebula 5.2 using centos7 with 2 nodes, Now we want to setup HA cluster environment between both frontend nodes for sunstone UI. i also followed mention official link: [http://docs.opennebula.org/5.2/advanced\_components/ha/frontend\_ha\_setup.html](http://docs.opennebula.org/5.2/advanced_components/ha/frontend_ha_setup.html) ## But getting some issue on that: [root@node1 ~]# pcs status Cluster name: opennebula Stack: corosync Current DC: node1 (version 1.1.15-11.el7\_3.2-e174ec8) - partition with quorum Last updated: Fri Jan 27 12:46:56 2017 Last change: Mon Jan 23 17:35:55 2017 by root via cibadmin on node1 2 nodes and 2 resources configured Online: [node1 node2] Full list of resources: fence\_node1 (stonith:fence\_ilo\_ssh): Stopped fence\_node2 (stonith:fence\_ilo\_ssh): Stopped Failed Actions: - fence\_node1\_start\_0 on node2 ‘unknown error’ (1): call=19, status=Error, exitreason=‘none’, last-rc-change=‘Tue Jan 24 14:21:28 2017’, queued=0ms, exec=11646ms - fence\_node2\_start\_0 on node2 ‘unknown error’ (1): call=20, status=Error, exitreason=‘none’, last-rc-change=‘Tue Jan 24 14:21:28 2017’, queued=0ms, exec=11315ms - fence\_node1\_start\_0 on node1 ‘unknown error’ (1): call=27, status=Error, exitreason=‘none’, last-rc-change=‘Mon Jan 23 17:35:46 2017’, queued=0ms, exec=11574ms - fence\_node2\_start\_0 on node1 ‘unknown error’ (1): call=33, status=Error, exitreason=‘none’, last-rc-change=‘Mon Jan 23 17:35:59 2017’, queued=0ms, exec=11592ms Daemon Status: corosync: active/enabled pacemaker: active/enabled pcsd: active/enabled * * * Also i setup in httpd.conf on both nodes: ## \ SetHandler server-status Order deny,allow Deny from all Allow from 127.0.0.1 Please suggest us how to resolve it. ======================================================= [root@node1 ~]# pcs config Cluster Name: opennebula Corosync Nodes: node1 node2 Pacemaker Nodes: node1 node2 Resources: Group: apache Resource: httpd\_vip (class=ocf provider=heartbeat type=IPaddr2) Attributes: ip=192.168.40.100 cidr\_netmask=24 Operations: start interval=0s timeout=20s (httpd\_vip-start-interval-0s) stop interval=0s timeout=20s (httpd\_vip-stop-interval-0s) monitor interval=10s timeout=20s (httpd\_vip-monitor-interval-10s) Resource: httpd\_ser (class=ocf provider=heartbeat type=apache) Attributes: configfile=/etc/httpd/conf/httpd.conf statusurl=http://127.0.0.1/server-status Operations: start interval=0s timeout=40s (httpd\_ser-start-interval-0s) stop interval=0s timeout=60s (httpd\_ser-stop-interval-0s) monitor interval=10 timeout=20s (httpd\_ser-monitor-interval-10) Stonith Devices: Resource: fence\_node1 (class=stonith type=fence\_ilo\_ssh) Attributes: pcmk\_host\_list=node1 ipaddr=202.xx.xx.135 login=… passwd=… action=reboot secure=yes delay=30 Operations: monitor interval=20s (fence\_node1-monitor-interval-20s) Resource: fence\_node2 (class=stonith type=fence\_ilo\_ssh) Attributes: pcmk\_host\_list=node2 ipaddr=202.xx.xx.136 login=… passwd=… action=reboot secure=yes delay=30 Operations: monitor interval=20s (fence\_node2-monitor-interval-20s) Fencing Levels: Location Constraints: Ordering Constraints: Colocation Constraints: Ticket Constraints: Alerts: No alerts defined Resources Defaults: No defaults set Operations Defaults: No defaults set Cluster Properties: cluster-infrastructure: corosync cluster-name: opennebula dc-version: 1.1.15-11.el7\_3.2-e174ec8 have-watchdog: false no-quorum-policy: ignore Quorum: Options: ---
