Finally we installed python-ctypes-1.0.2-2.el5.i386 on centos5.7 with
cobbler 2.3.1 package build from git source
and now cobblerd starts fine :-)
remember error was:
ImportError: No module named ctypes
Now I will reconsider migrating to a centos6 to host our cobbler server,
but I'am glad I have a procedure to do it if necessary.
Regards .

Yes -- and good point. The ctypes issue is news to me but I wasn't
around when it came up.
Given that, you should be able to get just as far with a rsync of
/var/lib/cobbler, /etc/cobbler, and /var/www/cobbler ... possibly with
a small bit of trial and error.

Good, I suppose you meant "cobbler replicate" !
however to do that I understand that cobblerd should be running on the
original server.
now that I broken my cobbler installation by upgrading to 2.3.1, I supose I
first need to downgrade to 2.2.1 in order to be able from a fresh installed
centos 6 with cobbler 2.3.1 to "replicate" from a repaired 2.2.1.
So my first step now is to downgrade the broken original server to 2.2.1 ?
is it just a matter of "yum downgrade cobbler-2.2.1-1.el5" ?
any dependencies problem I might run into ?
Thanks for the advices.

"cobbler reposync" does exactly this.

unfortunatly, there's no clean and secure way to upgrade (yum) from centos 5
to 6, cf
https://www.centos.org/modules/newbb/viewtopic.php?topic_id=32089
everywhere on centos site I see that the only clean way is to reinstall a
centos6 from scratch
I've got ~400Go of distribs+repos and hundreds of systems recorded on my
centos5.7 cobbler broken installation,
moving all that to a new cobbler system on centos6 from scratch will be a
long journey
is there a way to "export" the cobbler "database" (systems, profiles ...)
and in parallel moving distrib and repo directories with a simple cp/rsync
so that I get all my current cobbler object on a fresh installed centos6 ?
Otherwise, can I downgrade from rpm 2.3.1 to 2.2.1 in order to make my
cobbler production server to run again ?
Thanks.

Yes, I had this issue too. The problem is in python.. It's a known issue. I
fixed it by upgrading to centos6...

Any idea of what could be wrong ?
you told me to check potential .rpmnew files, there are 2 in /etc/cobbler:
[root@cobbler cobbler]# ls -ltra /etc/cobbler/*.rpmnew
-rw-r--r-- 1 root root 17205 Jan 11 16:10 /etc/cobbler/settings.rpmnew
-rw-r--r-- 1 root root 3266 Jan 11 16:10 /etc/cobbler/modules.conf.rpmnew
could this be related ?
thanks.

You should be fine. Backing up /var/lib/cobbler is smart though, and
pay attention to any .rpmnew files created.

OK, I got the latest source and made the rpms
# ls
cobbler-2.3.1-1.noarch.rpm koan-2.3.1-1.noarch.rpm

My cobbler installation is running on a centos5.7 system
# rpm -qa | grep -i cobbler
cobbler-web-2.2.1-1.el5
cobbler-2.2.1-1.el5
can I blindly upgrade those packages with the 2.3.1, or should I do
something before ?
where is the cobbler "database", config files , settings that I should
care about before upgrade ?
is there an upgrade page recommendation ? I found that related:
https://github.com/cobbler/cobbler/wiki/Relocating%20Your%20Install
but I'am afraid of bracking our installation by upgrading with a simple
yum localinstall cobbler*2.3.1*, should I ?
Thanks.

In the tread it is mentioned that it should be corrected in 2.3.1
where can I get 2.3.1 !? and a SRPMS so that I can recompile to the
latest release ?
Hi,
2.3.1 is the current development version, you can get it by pulling the
source with git and run 'make rpms'
