cobbler with no local mirroring?
by Matthew Miller 09 Jul '10

09 Jul '10

I know, installation server with batteries included... but we've got this connection to the power grid already up and running and would like to use that but still use cobbler. :) Basically, we've got a mirror server already. It has plenty of resources, and it's set up to automatically sync and so on. I'd therefore like to avoid duplicating effort (and wasting disk space) in cobbler, and point entirely at that remote mirror. The "Non-Import (Manual) Workflow" with --mirror-locally=N seems to get us part way there, but we still need to do things like "distro add" pointing to local kernel/initrd files This can't be that uncommon of a use case, can it? I must be missing something. Is there a secret way to distro add (or better yet "cobbler import") with the equivalent of --mirror-locally=N? Thanks! (Oh, related question: if one is doing --mirror-locally=N, does cobbler reposync do anything?) -- Matthew Miller mattdm(a)mattdm.org <http://mattdm.org/>

cobbler profile add --parent doesn't seem to inherit distro properly (v2.0.3)
by Msquared 08 May '10

08 May '10

Hi! I have a (CentOS 5.4) machine that's running Cobbler 2.0.3, which was upgraded from Cobbler 1.6.x. Now I can't create any sub-profiles that work. My first problem was that "--inherit" doesn't seem to exist in Cobbler 2, but it looks like "--parent" has taken its place. Now onto the main problem. With Cobbler 1.6.x, I could create a sub-profile like so: cobbler profile add \ --name=core-vm \ --inherit=centos-5-4-xen-x86_64 \ --kickstart=/var/lib/cobbler/kickstarts/sample.ks \ --repos="centos-5-x86_64-base centos-5-x86_64-extras centos-5-x86_64-updates epel-5-x86_64" \ --name-servers=192.168.1.254 \ --name-servers-search=mydomain.com.au \ --virt-ram=768 \ --virt-file-size=12 \ --virt-path=vgvirt After the upgrade to Cobbler 2, I tried to create a similar sub-profile, like so: cobbler profile add \ --name=core-vm-test \ --parent=centos-5-4-xen-x86_64 \ --kickstart=/var/lib/cobbler/kickstarts/sample.ks \ --repos="centos-5-x86_64-base centos-5-x86_64-extras centos-5-x86_64-updates epel-5-x86_64" \ --name-servers=192.168.1.254 \ --name-servers-search=mydomain.com.au \ --virt-ram=768 \ --virt-file-size=12 \ --virt-path=vgvirt The sub-profile appears to have been created OK, but in the WUI the new sub-profile has an empty Distro: Name Distro Actions centos-5-4-x86_64 centos-5-4-x86_64 Edit ... centos-5-4-xen-x86_64 centos-5-4-xen-x86_64 Edit ... core-vm <<inherit>> Edit ... core-vm-test Edit ... rescue-centos-5-4-x86_64 centos-5-4-x86_64 Edit ... When I try to use koan to create a VM based on the new sub-profile, it fails: [root@kane ~]# koan --virt --server=cobbler --system=testserv3 --static-interface=eth0 - looking for Cobbler at http://cobbler/cobbler_api - reading URL: http://192.168.1.11/cblr/svc/op/ks/system/testserv3 install_tree: http://192.168.1.11/cblr/links/centos-5-4-xen-x86_64 libvirtd (pid 3593) is running... downloading initrd initrd.img to /var/lib/xen/initrd.img url=http://cobbler/cobbler/images/~/initrd.img - reading URL: http://cobbler/cobbler/images/~/initrd.img Traceback (most recent call last): File "/usr/lib/python2.4/site-packages/koan/utils.py", line 130, in urlread fd = urllib2.urlopen(url) File "/usr/lib64/python2.4/urllib2.py", line 130, in urlopen return _opener.open(url, data) File "/usr/lib64/python2.4/urllib2.py", line 364, in open response = meth(req, response) File "/usr/lib64/python2.4/urllib2.py", line 471, in http_response response = self.parent.error( File "/usr/lib64/python2.4/urllib2.py", line 402, in error return self._call_chain(*args) File "/usr/lib64/python2.4/urllib2.py", line 337, in _call_chain result = func(*args) File "/usr/lib64/python2.4/urllib2.py", line 480, in http_error_default raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) HTTPError: HTTP Error 404: Not Found Traceback (most recent call last): File "/usr/lib/python2.4/site-packages/koan/app.py", line 1024, in get_distro_files utils.urlgrab(initrd,initrd_save) File "/usr/lib/python2.4/site-packages/koan/utils.py", line 161, in urlgrab data = urlread(url) File "/usr/lib/python2.4/site-packages/koan/utils.py", line 143, in urlread raise InfoException, "Couldn't download: %s" % url InfoException: "Couldn't download: http://cobbler/cobbler/images/~/initrd.img" error downloading files [root@kane ~]# It looks like its missing the distro component of the path to the initrd image: http://cobbler/cobbler/images/~/initrd.img I'm sure there should be a distro name where the '~' is. If I create a VM based on the original sub-profile (created with Cobbler 1.6.x), then it works fine. I can even create a copy of a sub-profile, and use that as the basis for a system; that system will also install fine. Any ideas where to start with this? Is this a regression, or have I missed something that's different with Cobbler 2? Regards, Msquared...

Including python in kickstarts
by Chris Sarginson 30 Apr '10

30 Apr '10

Hi, Has anyone got any documentation, hints or samples of python inside a kickstart? Specifically I need to connect to a MySQL db when displaying the kickstart to pull some information from a database that will be used to configure the servers settings, and I'm having some trouble getting to grips with it. Cheers Chris

Creating and using Custom YUM Repos with Cobbler?
by lists＠truthisfreedom.org.uk 29 Apr '10

29 Apr '10

Hi all, I'm using cobbler with Puppet and so far it's going really well using cobbler for class management. I've run into an issue whereby I need to install custom RPMS on boot using cobbler and the only way I can currently find to do this is to setup a custom repo (using mrepo or similar) then put that as a mirror in cobbler and let cobbler "import" the files and the repo. Is there any way to have cobbler perform the initial creation of the repo and then publish packages straight into the repo that is managed by cobbler? If that's not clear, let me know and I'll do my best to explain further! Thanks in advance, Matt.

New profile and kickstart
by Marcelo Garcia 28 Apr '10

28 Apr '10

Hi I created a new profile[1] to make a minimal install using a kickstart. When I boot up the client, I see the profile, but after a while the installation fails because it could not find the kickstart file in "http://127.0.0.1/cblr/svc/op/ks/profile/centos_64_minimal". (1) Which URL is this? (2) Why is looking for a kickstart with the name of the profile if I specified the name of the kickstart file: "minimal-ks.cfg"? Thanks Marcelo [1] [root@tannat ~]# cobbler profile add --name="centos_64_minimal" --distro=CentOS-5.4-x86_64 --kickstart=/var/lib/cobbler/kickstarts/minimal-ks.cfg

Cobbler and Solaris
by mark＠proseconsulting.co.uk 23 Apr '10

23 Apr '10

BODY { font-family:Arial, Helvetica, sans-serif;font-size:12px; } We're considering Cobbler for the provisioning of RHEL and Solaris hosts. The RHEL bit is easy. However, the question has arisen - how easy would it be to set-up Cobbler so that it could produce the necessary Solaris x86 PXE stuff, and JumpStart configuration (the latter for both x86 and SPARC). A quick trawl of the web reveals sparse discussion of this subject, and a statement on 24th Feb 2009 from icontender "I think it would be really difficult to add direct solaris support. The jumpstart architecture is really advanced and is able to do many things that Kickstart cannot." Mind you, that comment related to JET, which is a JumpStart add-on that we wouldn't be using. Has any work been put into this in Cobbler yet? Do you know of anyone who is using Cobbler in this way? What are your general thoughts on the future of Cobbler for non-Linux platforms? Thanks in advance for any advice you can offer me on the above. Best regards, Mark Bannister.

Re: Updated menu.c32
by Steven L. Seed 23 Apr '10

I'm experiencing this same problem with menu.c32 and localboot. In your posting, you mention changing the real mode segments. I'm not familiar with this. Can you explain? Updated menu.c32 Vreman, Peter - Acision peter.vreman atacision.com Tue Mar 3 15:39:55 UTC 2009 Previous message: Updated menu.c32 Next message: 'cobbler import' error: local variable 'datestamp' referenced before assignment Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] > I've had this problem in the past, on RHEL4.2 systems.

The bug I'm having is not menu.c32 related as I thought. The problem is that only localboot is not working. All other network-boot entries are working. It is a generic HP Proliant-pxelinux problem, see also http://www.gossamer-threads.com/lists/syslinux/users/8742 . I have tested with the latest syslinux pxelinux.0. When I change the real mode segments to 5000h-6000h-7000h then I can can also use the localboot. Regards, Peter This e-mail and any attachment is for authorised use by the intended recipient(s) only.
