5.3. Viewing STONITH information

To see how STONITH configures your fencing devices, run the pcs stonith show --full command from the overcloud: 

$ sudo pcs stonith show --full
 Resource: my-ipmilan-for-controller-0 (class=stonith type=fence_ipmilan) 1
  Attributes: pcmk_host_list=overcloud-controller-0 ipaddr=10.100.0.51 login=admin passwd=abc lanplus=1 cipher=3
  Operations: monitor interval=60s (my-ipmilan-for-controller-0-monitor-interval-60s)
 Resource: my-ipmilan-for-controller-1 (class=stonith type=fence_ipmilan)
  Attributes: pcmk_host_list=overcloud-controller-1 ipaddr=10.100.0.52 login=admin passwd=abc lanplus=1 cipher=3
  Operations: monitor interval=60s (my-ipmilan-for-controller-1-monitor-interval-60s)
 Resource: my-ipmilan-for-controller-2 (class=stonith type=fence_ipmilan)
  Attributes: pcmk_host_list=overcloud-controller-2 ipaddr=10.100.0.53 login=admin passwd=abc lanplus=1 cipher=3
  Operations: monitor interval=60s (my-ipmilan-for-controller-2-monitor-interval-60s)

The --full option returns fencing details about the three Controller nodes.

This output shows the following information for each resource:

  • IPMI power management service that the fencing device uses to turn the machines on and off as needed, such as fence_ipmilan.
  • IP address of the IPMI interface, such as 10.100.0.51.
  • User name to log in with, such as admin.
  • Password to use to log in to the node, such as abc.
  • Interval in seconds at which each host is monitored, such as 60s.
