Hi Mario,

No, not for some time.  Indeed this was a 1.4 issue that was resolved
in 1.5.  And to be honest, I don't even bother with anything less than
1.8 these days.  Cert instructs all test centers to install from the
maas/stable ppa, so they get 1.8 out of the box.

[Bug 1266840] Re: maas-dns failed to install completely on Trusty

[Mike Pontillo]

As Jeff said, I believe this is fixed in MAAS 1.7.

I worked on a related race condition having to do with migrating MAAS-
managed BIND variables to the MAAS database.

If you are installing MAAS on a machine which will *not* host the MAAS
database, there is still somewhat of a race condition, in that we cannot
fully migrate the BIND configuration to the MAAS database unless the
database is up and running.

On MAAS 1.7, if you hit this situation, you can run:

sudo maas-region-admin edit_named_options --migrate-conflicting-options

This will rewrite the BIND configuration to ensure that MAAS does not
duplicate any BIND options (which would result in the symptom above:
BIND failing to start).

[Bug 1266840] Re: maas-dns failed to install completely on Trusty

[Mario Splivalo]

Hi, Jeff.

Is this still the issue? I just tried deploying maas with ubuntu trusty,
installing just 'maas' package, which then install everything that was
needed (incuding maas-dns).  The maas version in trusty is 1.5, and I
had no issues with installing.

Then I added maas stable ppa, and upgraded to maas 1.7, also no issues.

To be complete, I trashed my test env, created clean one, added maas
stable ppa and installed maas from there - also no issues.

(I did all my tests in trusty lxc container).

I see you were testing with 1.4+bzr1789+dfsg-0ubuntu1, where maas-dns is
currenlty on 1.5.

Reading that comment, it suggests that the named.conf.maas file should
be empty by design so I created one like so:

sudo touch /etc/named/maas/named.conf.maas

and restarted bind and apache.

Then, I deleted my node and retried and it successfully commissioned and
declared.

From there, I was able to access it via the UI and click Commission
Node and the node turned on and successfully booted the commissioning
image. (It was failing before because DNS was never started, causing the
commissioning image to hang)
