Configure Corosync:
  This will configure the cluster messaging layer.  You will need
  to specify a network address over which to communicate (default
  is eth0's network, but you can use the network address of any
  active interface).

  Network address to bind to (e.g.: 192.168.1.0) [10.67.160.0]
  Multicast address (e.g.: 239.x.x.x) [239.143.9.201]
  Multicast port [5405]

Configure SBD:
  If you have shared storage, for example a SAN or iSCSI target,
  you can use it avoid split-brain scenarios by configuring SBD.
  This requires a 1 MB partition, accessible to all nodes in the
  cluster.  The device path must be persistent and consistent
  across all nodes in the cluster, so /dev/disk/by-id/* devices
  are a good choice.  Note that all data on the partition you
  specify here will be destroyed.

SBD is already configured to use /dev/disk/by-path/ip-10.67.160.200:3260-iscsi-iqn.2018-01.suse.com:larry-jenkins-test-sbd-lun-0 - overwrite (y/n)? n
