How can I update the interfaces on a MAAS controller?


I’ve deployed a MAAS region+rack setup and since then we’ve added additional interfaces to the server. However, MAAS does not show the new interfaces in the controller, and I can’t find a way to add them or to make it redetect them. I’ve also tried a snap restart maas.


What version of MAAS have you installed?

I’ve got 2.9.2. Though I must admit it’s my own snap build of MAAS due to me adding support for Moonshot Chassis 2.0. So it’s quite possible that I’ve done something wrong. Our plan is to set up a test server with the official snap just to make sure, but I don’t think I’ll get a chance to do that until late next week.

Just though I’d ask here because I’ve been trying all kinds of CLI commands to try and create the interface, and ended up just wiping the database and starting again (under a bit of pressure to get something working).

This is very strange. MAAS should detect new interfaces and periodically report them.

Could you check both region and rack logs for errors?

If it’s easier, you could also file a bug on and attach logs there.
In a snap setup, they’re under /var/snap/maas/common/log/.
