Description of problem: Due to spacewalks changes to cobbler's settings and modules.conf cobblerd no longer starts. Version-Release number of selected component (if applicable): Updating cobbler from 2.0.11-2.el6 to 2.2.1-1.el6 All packages on the system are up to date including spacewalk repo (1.7) CentOS 6.2 with CentOS base, updates, and epel repository How reproducible: Always Steps to Reproduce: 1. Upgrade cobbler to newest version (2.2.1-1.el6) 2. Cobblerd fails to start 3. Downgrade cobbler to 2.0.11-2.el6 4. Cobblerd starts fine Actual results: Cobblerd fails to start Expected results: Cobbler updates without a problem. Without cobbler running kickstarts and several other functions fail Additional info: [root@rh-spacewalk cobbler]# yum update cobbler <snip> Updating : cobbler-2.2.1-1.el6.noarch 1/2 warning: /etc/cobbler/modules.conf created as /etc/cobbler/modules.conf.rpmnew warning: /etc/cobbler/settings created as /etc/cobbler/settings.rpmnew Stopping cobbler daemon: [ OK ] Starting cobbler daemon: Traceback (most recent call last): File "/usr/bin/cobblerd", line 76, in main api = cobbler_api.BootAPI(is_cobblerd=True) File "/usr/lib/python2.6/site-packages/cobbler/api.py", line 130, in __init__ self.deserialize() File "/usr/lib/python2.6/site-packages/cobbler/api.py", line 795, in deserialize return self._config.deserialize() File "/usr/lib/python2.6/site-packages/cobbler/config.py", line 266, in deserialize raise CX("serializer: error loading collection %s.

After the cobbler update, would the following procedure: # cp /etc/cobbler/modules.conf /etc/cobbler/modules.conf.bak # cp /etc/cobbler/settings /etc/cobbler/settings.bak # cp /etc/cobbler/modules.conf.rpmnew /etc/cobbler/modules.conf # cp /etc/cobbler/settings.rpmnew /etc/cobbler/settings # cobbler-setup # service cobblerd restart lead you to a functioning setup?
That allowed cobbler to start, however the rpmnew configs don't contain any of the settings related to spacewalk, so spacewalk was still non functional. I just included those lines here to show that this is an issue with the customization related to spacewalk. So from the output above we can see that the spacewalk configs only work with the old version, and the versions from the rpm work with both the new and the old cobbler version.
I just tested with the settings file from spacewalk, and the modules.conf from the rpm and it appears that the problem is only in modules.conf (like the error message says) With modules.conf from the rpm [root@rh-spacewalk cobbler]# diff modules.conf modules.conf.bak 22c22 < module = authn_denyall --- > module = authn_spacewalk 72,85d71 < # tftpd: < # chooses the TFTP management engine if manage_tftp is enabled < # in /etc/cobbler/settings, which is ON by default. < # < # choices: < # manage_in_tftpd -- default, uses the system's tftp server < # manage_tftpd_py -- uses cobbler's tftp server < # < # for more information: < # https://fedorahosted.org/cobbler/wiki/ManageTftp < < [tftpd] < module = manage_in_tftpd < I figured that the authn_spacewalk module was the problem, so to rule out the tftpd section as the problem I removed it from modules.conf (from the rpm) and I came up with the same error. So it looks like the missing tftpd section is where the issue is coming up. So I copied my modules.conf.bak to modules.conf and added the tftpd section to the original conf. Now cobbler, and spacewalk are working on the new version.
As a part of fix for bug #812794 we implemented new script called: spacewalk-setup-cobbler which will correctly configure cobbler v2.2 for use w/ Spacewalk. I'm closing this report as a duplicate of #812794. *** This bug has been marked as a duplicate of bug 812794 ***
