A small bug, I think, in adding yum repositories

by Dan White

I made a set of local yum repositories according to <https://access.redhat.com/kb/docs/DOC-35962> As an example, reposync --gpgcheck -l -n --repoid=rhel-x86_64-server-5 --download_path=/var/www/localRepo/rhel-x86_64-server-5 createrepo /var/www/localRepo/rhel-x86_64-server-5 and create an appropriate /etc/yum.repos.d/local.repo, naming my repo "local-rhel-x86_64-server-5" OK, so now I want to roll this into cobbler. So I say: cobbler repo add --name=local-rhel-x86_64-server-5 --mirror=http://my.server.org/localRepo/rhel-x86_64-server-5 --mirror-locally=false --keep-updated=false And then when I say: cobbler reposync I get this: running /usr/bin/wget -q http://my.server.org/localRepo/rhel-x86_64-server-5/repodata/repomd.xml -O /var/www/cobbler/repo_mirror/local-rhel-x86_64-server-5/.origin/repomd.xml received on stderr: /var/www/cobbler/repo_mirror/local-rhel-x86_64-server-5/.origin/repomd.xml: No such file or directory. And the target directory (/var/www/cobbler/repo_mirror/local-rhel-x86_64-server-5) is empty So I say: mkdir /var/www/cobbler/repo_mirror/local-rhel-x86_64-server-5/.origin and run cobbler reposync again, and get what looks like proper responses and proper contents of the directory. So, the question/bug is: Why isn't the ".origin" directory created before trying to wget the file into it ? “Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us.” Bill Waterson (Calvin & Hobbes)

A question about local mirrored repositories

by Dan White

What are the (dis)advantages about using cobbler directly to make a local repository mirror versus doing it separately with yum commands and then adding the repo to cobbler ? “Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us.” Bill Waterson (Calvin & Hobbes)

How to recover missing profiles and distros

by Leonid Flaks

Hi! I am not sure what happened, but all of a sudden all distos and profiles are not listed any more. I can't see them neither in CLI nor using web interface. However, all actual json files are there in /var/lib/cobbler/config/profiles.d/ and /var/lib/cobbler/distros.d directories. Does anybody know of an easy way to restore those except manually entering them from json files? All systems and repos are just fine. I tried to do 'cobbler sync', but it complained about the system referencing missing profile. This is cobbler 2.0.11 on Scientific Linux 6.0 Thanks, Leon

Replicate with rsync over SSH

by John Dunbar

Hi, I'm just about complete with a migration to 2.0 with everything working other than replication. I see it's trying to use rsync, which is blocked on our firewalls, how do I force it to rsync over SSH? Getting rsync open on our firewalls isn't an option. Thanks, John

$ks_meta?

by Urwin, Paul

Hi, At the top of my kickstart I have this: # --- Cobbler Details --- # name = $name # distro = $distro # profile_name = $profile_name # http_server = $http_server # hostname = $hostname # system_name = $getVar("system_name","") # interfaces = $interfaces.keys() # ks_meta = "$ks_meta" However the ks_meta line always just renders as is, the $ks_meta variable name doesn't get translated into a value: # --- Cobbler Details --- # name = myhostname # distro = rhel5.5 # profile_name = rhel5.5_default # http_server = 169.111.111.111 # hostname = myhostname.mydomain # system_name = myhostname # interfaces = ['vmnic0'] # ks_meta = "$ks_meta" Is this a known thing? Am I using the wrong variable name? How can I correctly display the contents of the metadata field? Thanks! Paul This communication is for informational purposes only.

cobbler as a monitoring "provider"

by Gerhardus Geldenhuis

Hi I am toying with the idea to write an addon for cobbler that will allow it to become an authorative source of servers in the same way as cobbler can/does provide a list of servers to a configuration management system like puppet. If you add a little bit of abstraction you could make it monitoring system agnostic. The idea is basically that for every server build or rebuild it will add/modify an entry in the monitoring system. Rather than this being something that is added in a custom script/snippet it could be more integrated. This is a very raw idea at present so just keen on thoughts or feel free to shoot it down if you think it is completely untenable. Regards -- Gerhardus Geldenhuis

Repo question.

Re: Repo question. (Dale, Christopher [Colloquium])

by Dale, Christopher [Colloquium]

So, i fixed this by manually deleting the .rpm file from /var/www/cobbler/repo_mirror/ and then I re-executed the cobbler reposync. This put the proper RPM into the directory. On the client I did a yum clean all and a yum install iperf and it worked. -- Christopher Dale | President and Forum Moderator mobile: 540-903-1775 | email: christopher.dale(a)colloquium.co web: http://www.colloquium.co | twitter: @colloquiumco<http://twitter.com/colloquiumco> | identica: @colloquiumco <http://identi.ca/colloquiumco>

I need some help building snippets

by Dan White

I have some python code that does what I want to do in a snippet, but I cannot translate it into something that will get past the cheetah compile/conversion. Just a few lines - here they are: <python code> import sys, ConfigParser cf=ConfigParser.ConfigParser() sys.stdout.write("cf=") print cf list=cf.read ( 'mysettings.cfg' ) sys.stdout.write("cfg file=") print list sys.stdout.write("sections=") print cf.sections() print cf.get ( 'MySection', 'field1' ) print cf.get ( 'MySection', 'field2' ) </python code> The file (mysettings.cfg) contains: [MySection] field1 = this field2 = that When I execute this python script, I get this output: cf=<ConfigParser.ConfigParser instance at (address)> cfg file=['mysettings.cfg'] sections=[MySection] this that Now to the cobbler/cheetah snippet: <snippet> #import ConfigParser #set $cf=$ConfigParser.ConfigParser() #echo 'cf=>' #echo $cf #echo '\n' #set $list=$cf.read ( 'mysettings.cfg' ) #echo 'cfg file=>' #echo $list #echo '\n' #set $sec = $cf.sections() #echo 'sections=>' #echo $sec #echo '\n' #set $one = $cf.get ( 'MySection', 'field1' ) #echo $one #set $two = $cf.get ( 'MySection', 'field2' ) #echo $two </snippet> But the cheetah fails in an odd (to me) way. First of all, the line: #set $list=$cf.read ( 'mysettings.cfg' ) fails unless I change it to : #set $list= cf.read ( 'mysettings.cfg' ) and then I get the following output: cf=<ConfigParser.ConfigParser instance at (address)> cfg file=[] sections=[] and then the script will fail on the "get" method calls Any suggestions / clues out there ? “Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us.” Bill Waterson (Calvin & Hobbes)
