I’m testing SLES12 SP3 HA Extension. When running ha-cluster-init in node 1, it returns error message as follows. From the man page, it mentions eth0 is the default network interface. Don’t understand why it cannot detect the network card. The workaround is to use -i option to specify eth0 and looks worked fine. When running ha-cluster-join in node 2, it returns the same error message. But this time, that workaround doesn’t work and it returns another error message as follows. I verified that node 1 and node 2 are able to login with each others via ssh without password. Do you have any idea to solve it?
“ERROR: cluster.init: Failed to determine default network interface”
hc-cluster-init -i eth0
Done (log saved to /var/log/ha-cluster-bootstrap.log)
ERROR: cluster.join: Failed to determine default network interface
ha-cluster-join -i eth0
ERROR: 1: cluster.join: Can’t invoke ha-cluster-init ssh_remote on 192.168.10.11
