Cobbler fail to edit profile kernel option

[Simon Monette]

When trying to edit a ks profile with cobbler on fuel 5.0 only the first argument of the --kopts parameter is taken,
Example:

#Current setting
[root@fuel ~]# cobbler profile report --name bootstrap |grep Kernel
Kernel Options : {'url': 'http://10.20.0.2:8000/api'}

#Edit profile
[root@fuel ~]# cobbler profile edit --name bootstrap --kopts "url=http://10.20.0.2:8000/api biosdevname=0 console=ttyS0,115200"

# Profile afterward:
[root@fuel ~]# cobbler profile report --name bootstrap |grep Kernel
Kernel Options : {'url': 'http://10.20.0.2:8000/api'}

If I invert the order of the parameters, again only the first argument will be taken,
Exemple:

#Edit profile
[root@fuel ~]# cobbler profile edit --name bootstrap --kopts "console=ttyS0,115200 url=http://10.20.0.2:8000/api biosdevname=0"

# Profile afterward:
[root@fuel ~]# cobbler profile report --name bootstrap |grep Kernel
Kernel Options : {'console': 'ttyS0,115200'}

I searched the cobbler documentation and the syntax did not appear to have change since the last release.
These commands worked with Fuel 4.1.

Thank you.

in 5.0 we added a field on the settings page to change the kernel options for the entire cluster so that they may be able to best suite your needs. This value can only apply after the bootstrap is complete, so may not be a good option for you.

Can you validate if you can change the setting from the cobbler web ui? https://<fuel node>/cobbler_web (cobbler:cobbler)

Confirmed works in 4.1 and not in 5.0

[Andrew Woodward (xarses)]

Confirmed that it works correctly inside the docker container.

As a workaround do

$ dockerctl shell cobbler

and then run commands in there.

Please feel free to ping here or on IRC if you still have issues.

Yes editing the profile with cobbler_web worked!

I was aware of the nice addition of the kernel options field in the setting page.
But as you pointed out it only take effect once everything is installed.

Having access to the serial port (the only I/O available on nodes) during bootstrap and the install phase helps a lot went issues occur.

This is related to docker shell and the alias I added as a helper for making the transition easier. Quoting strings doesn't work with the current code:
  lxc-attach --name "$id" -- $command

It strips quotes. I need to reparse params and force-quote each parameter. It's just something we didn't catch in time for 5.0.
