SCALE: multiple machines get the same MAC address for LACP interfaces

Thanks for tracking this down – I can confirm that your steps to manually regenerate the machine ID fix the problem for me.

thanks for confirming my theory. I know what the problem is and will work on a fix. The linux kernel uses that id to generate unique mac addresses for virtual interfaces so it explains why all 3 of your machines got the same mac address.

However, the fix is relatively simple. You can run these commands on each node and then reboot them to ensure everything gets generated at boot using the new id.

1. "rm /var/lib/dbus/machine-id"
2. "rm /etc/machine-id"
3. "systemd-machine-id-setup"
4. "shutdown -r now" (reboot)

Once it comes up, all 3 machines should have different mac addresses. This change should be permanent as well.

All three machines have the same machine-id somehow: b9bee86c6c6f406cb063ffac562cb342
