I discussed this with cgregan on IRC and I think we came to the conclusion that the MAAS/curtin bug is simply that the two kernels (commissioning vs. ephemeral deployment) gather different (or missing) unique identifiers for each drive.
To validate that, I would run the following on each kernel on the problematic systems: find /dev/disk -type l | xargs ls -1l | awk '{ print $9, $10, $11 }' | sort -k2 This will tell us which unique identifiers each kernel found to identify each disk, and sort by the endpoint block device, to make it easier to identify what might be missing for each drive. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1651602 Title: [2.1.1] MAAS has nvme0n1 set as boot disk, curtin fails Status in MAAS: Invalid Status in linux package in Ubuntu: Invalid Status in linux source package in Xenial: Fix Committed Bug description: MAAS Version 2.1.1+bzr5544-0ubuntu1 (16.10.1) Deploying Xenial Nodes 1) Deploy MAAS 2.1.1 on Yakkety 2) Associate Juju 2.1 beta3 3) Juju deploy Kubernetes Core Nodes begin to deploy but fail Installation failed with exception: Unexpected error while running command.
