using maas version 3.0.0
I have an issue where two separate rack controllers (running in different locations in different subnets) for some reason register with the exact same system_id.
product_uuid is different on both machines (as I thought maybe there is a collision there).
cat /sys/class/dmi/id/product_uuid 4c4c4544-0048-3110-8032-c4c04f304433
cat /sys/class/dmi/id/product_uuid 4c4c4544-004e-5710-8035-b3c04f465732
I tried to delete both rack controllers. Completely removed them from maas region controller.
Then I registered first one. It registered with a new system_id now.
Then I registered a second one. And it took the same system_id as a first one. And now first rack controller is gone and instead it is showing second rack controller instead of first one.
MAC addresses on both machines are different.
What else does MAAS is using to id the system? As obviously there is some sort of collision, but I cannot find where it is coming from.
