I came across the following error message while running ha-cluster-init on node2:  
`ERROR: cluster.init: Failed to determine default network interface`

There were no meaningful clues left in the ha-cluster-bootstrap.log file, as can be seen from the screencap below.

After validating that the node’s network interfaces had been properly configured and were active, I went ahead and re-ran the command with the `-i bond0` option to manually specify the desired network interface.  
The node was then able to join the cluster.

Someone mentioned encountering similar issues in today’s webinar.  
Is this failure caused by a known issue, and how would the instructor recommend we fix it?

Thanks.

I no longer have the error on screen, because the two nodes have been enjoyng a friendly fencing race.  
But for what it’s worth, running `ha-cluster-remove` results in the same error (and this command has no -i option).

Did you add the Default IPv4 Gateway when configuring the network settings? That would cause this issue. Check Lab 4-1, Task 4, Step 6. You have to configure the gateway on both node 1 and node 2.
