MAAS

Unable to commission nodes

Asked by Cavendish McKay on 2012-07-04

I have installed MAAS and powered on some nodes to let them declare themselves to the MAAS server (they now show up as "Declared" in the nodes list). When I try to "Accept and Commission", however, I get back a page saying "Internal Server Error". The apache logs don't show anything (neither an attempt to access something, nor any information about an error).

If instead I try to add the MAC addresses manually, the add node page gives the message:
Unable to create Node: Commissioning script is missing: etc/maas/commissioning-user-data

Looking in /etc/maas, the needed script is not, in fact, missing.

Can someone give me a pointer as to what to try next?

Thanks,

This definitely looks like a bug (I've filed https://bugs.launchpad.net/bugs/1021382). We will investigate some more by in the mean time:
a) When you're getting the "Internal Server Error", could you please have a look at the files in /var/log/maas/ and especially maas.log to see if you can find more information about the error?
b) When you're adding the MAC addresses manually, could you try adding the line:
COMMISSIONING_SCRIPT = 'etc/maas/commissioning-user-data'
at the end of the file /etc/maas/maas_local_settings.py?
(Note that you'll need to restart MAAS for that change to apply: sudo /etc/init.d/apache2 restart

Here is the relevant entry from maas.log:

ValidationError: [u'Commissioning script is missing: etc/maas/commissioning-user-data']

So, the message is the same in either case, though it presents differently.

Adding COMMISSIONING_SCRIPT = '/etc/maas/commissioning-user-data' (note the leading slash; different from what you suggested) to /etc/maas/maas_local_settings.py makes the problem go away.

All right, so the bug I filed is definitely confirmed, thanks for reporting this.

Yeah, my mistake my suggestion was indeed to add the leading slash ;)

Can you help with this problem?
