You have been subscribed to a public bug:
The udev package provides /lib/udev/rules.d/60-persistent-storage.rules
which creates two symlinks for nvme devices, under /dev/disk/by-id/. The
first link name includes the device wwid and the second includes the
device model/serial. The commission script selects the first link
discovered and subsequently attempts to store it in a FilePath field,
which allows for 100 characters. Since the wwid link is greater than 100
characters an exception is thrown, causing not only the nvme device not
to be registered but all other storage devices as well. Although
commissioning completes there is no storage assigned, which makes
deployment of the node impossible.
This issue has blocked all test runs performed by the CDO-QA test
infrastructure, since every run installs MAAS on a fresh machine and
commissions new nodes. The failure is seen when installing from either
ppa:maas/next (2.2.0~beta2) or ppa:maas/stable (2.1.3+bzr5573).

After re-commissioning one of the servers with ssh enabled the attached
log files were collected. Please note that from the shell it can be seen
that block devices are discovered and even the commissioning output
found in /tmp/user_data.sh.IK9yVp/out/00-maas-07-block-devices lists
devices (see attached), where-as this file is shown as a 0 byte file
from the GUI (see screen shot).
There are 'HTTP Error 500: INTERNAL SERVER ERROR' errors in cloud-init-
