[2.2] rackd is not refreshing is commissioning information

seems that rackd.conf tries to access 127.0.0.1 by default instead of whatever is configured in /etc/maas/rackd.conf.

I hardcoded an IP address in /usr/lib/python3/dist-packages/provisioningserver/refresh/__init__.py, but while I dont see the errors in the logs anymore, the commissioning doesn't seem to have been run at all, or if it has, it hasn't been updated.

after multiple restarts and changes while doing other things, it finally refreshed (this after probably 5 hours after having installed maas, so there's definitely an issue. Specially due to #1).

note that it refreshed with the work around in #2

I just built master and went to do a fresh install and my setup script failed. In rackd.log the following error is repeated a number of times. /etc/maas/rackd.conf and /etc/maas/regiond.conf are both owned by root:maas with their permission set to 640. Setting both to 660 fixed the problem for me.

Did packaging change the permission of these files? I used make package-dev to build the deb files.
If the permission is correct MAAS needs to be opening these files with read only permission. The error below happens when we try to touch it, we could touch it only if it doesn't exist.

PermissionError: [Errno 13] Permission denied: '/etc/maas/rackd.conf'

    os.close(os.open(path, os.O_CREAT | os.O_APPEND, mode))

Nothing has changed from the Maas side and I don't think this is related
provided Maas I tested against for this bug is 2.2.0 from the archive.

That said, the config file permission are fixed by the code in case they
are wrong.

@Lee, let me re-state. The issue is present and it is not related to the issue you came across. I have a MAAS that has been running for over 24hours just fine, and the rack cannot update its commissioning information because the rack is trying to use '127.0.0.1' instead of what's configured in /etc/maas/rackd.conf maas_url.

Can you post the logs of the rack controller this is happening on? http://127.0.0.1:5240/ is the default value when the maas_url isn't found in the config file which is why I thought the two might of been related.

While trying to debug this issue I came across lp:1705774, reverting 48efa8062b866c9b1b82fdca6be2c0e7067e472e solved the issue for me, I'm wondering if that commit is causing this error as well.

Lee,

Racks.conf as said, points to an IP. Nothing strange in logs other than
what I already said. Everything g else works as expected (deploys,
commissioning etc)

Is a region controller also running on that machine? When a refresh occurs on a region and rack controller the region process runs the refresh and sends the data to itself over HTTP(localhost).
