Hi, I manage a cluster using MAAS. I’m starting to upgrade the nodes from 14.04 to 18.04, and some nodes are getting stuck in a boot loop with 18.04. Specifically, when the node gets to:
Loading ubuntu/amd64/generic/bionic/daily/boot-initrd… ok
The node reboots immediately. This repeats once it reboots. Here are some key details:
-
This occurs during Commissioning using 18.04. I can get Commissioning to work by switching to 16.04. However, I get the same problem when I go to Deploy 18.04.
-
The issue occurs every time with a subset of nodes. However, other nodes with identical hardware do not have this problem.
Could this be related to the fact that I had a messy upgrade of my MAAS server from 14.04 to 16.04. Is there a good way to install a new MAAS server from scratch and point the nodes to it?
Sorry for a newbie question, but I’ve lost several days trying to debug this issue on my own.
