Public bug reported:
Hi,
Deploying a trusty server which has configured 2 raid devices(one for
the system, and one for storage), I try to cache the storage raid with
bcache on MaaS. The deployment proceed correctly if I select the hwe-t
kernel before deploying, however, for any newer kernel it will fail. For
hwe-u and hwe-v, maas reports the following output:
Creating new GPT entries.
The operation has completed successfully.
Error: /dev/nvme0n1: unrecognised disk label
