Node passes commissioning without any disks

[Jason Hobbs]

This is with MAAS 1.7.1~rc1+bzr3322-0ubuntu1~trusty1.

This node reports storage size 1 in the UI, but has no disks attached Here is the LSHW XML:
http://paste.ubuntu.com/9481485/

This node is now in the 'Ready' pool but it isn't really usable because it doesn't have any disks. MAAS doesn't tell me that is has no disks - I just noticed the storage size looked off. I would prefer the disk not go to 'Ready' state if it's not ready to use.

Note that according to bug 1402280 that lshw can't be fully trusted anyway, so this may require deeper changes in order to be fully fixed.

I just ran into this myself when trying to install on a node which I discovered had no disk. Strangely, it reported having 1 GB of disk after commissioning, and I got a strange curtin error in the install log; I'll attach the screenshots that show this off.

Yeah -- same here. Of my 15 hosts, 13 of them show 1 GB disks. I'm assuming it's somehow trying to provision with the ISO it PXE booted with (as opposed to the 1 TB disk that all nodes are provisioned with, and the other two found correctly) :

        - lshw:node:
            id: disk
            claimed: true
            class: volume
            handle: SCSI:06:00:00:01

Looks like this is directly related to, but not quite a duplicate of, this: https://bugs.launchpad.net/maas/+bug/1318382

What version of MAAS are you running Ken?

1.7 has much better disk identification than 1.5 does and will likely fix
the issues you're seeing with incorrect disk detection. You can pick it up
from the maas-maintainers/stable

Sorry -- should have said. Using 1.7.2 from the PPA.

Thanks - could you file a new bug about the 1GB disk identification
behaviour you're seeing?

Thanks,
Jason

Note that for diskless node support we probably wouldn't want this to be fatal.
