Getting rid of bad cobbler metavariables
by Adam Rosenwald 23 Jan '10

23 Jan '10

A FAQ that I have brought up on numerous occasions on IRC involves 'getting rid of bad cobbler metavariables'. If I were to set a wrong ks_meta variable NAME, how do I get rid of the NAME without taking out ks_meta entirely. E.g. `cobbler system add --name=NAME --ksmeta='arg0=val0 arg1=val1 *art2*=val2 ... argN=valN' ...` There are quite a number of scenarios where I don't want to remove all of ksmeta, but only a mistyped variable name. I have heard about the '!ARG' syntax: E.g. `cobbler system edit --in-place --name=NAME --ksmeta='*!art2*'` Supposedly this syntax will, upon deserialization of the JSON, clear the ks_meta namespace of *art2*; however, upon issuing a report on a given entity, the flawed variable will still appear along with the negated variable. I.e. ks_meta : 'arg0=val0 arg1=val1 *art2*=*val2* ... argN=valN *!art2*' For those who make use of this data for inventory or other purposes, the '!VAR' notation does not cut it. I would like a definitive explanation of how to remove bad metavariables irrespective of deserialization. Thanks, - A.

Inconsistency between cobbler webui (system list) and command line

Hello all! Doing some system renaming via the system webui, after making my changes I sync'ed and noticed that the webui differs form what the command lind reports cobbler system list 00_09_6B_DA_71_46 00_16_3E_02_10_41 00_16_3E_41_55_2A Dalaran Sol WebProxynew antivirus apollo2 calendar chalkboard eden eva f11base genesis ie-linux iesurveys images iris naxx ox pluto torquetest treekiller zeusdev2 zord == cobbler == cobbler version cobbler 1.6.6 build date : Fri Jun 12 16:22:03 2009 Copyright (C) 2006-2008 Red Hat, Inc.

RHEL 5.3 failure: repodata/primary.xml.gz
by CLIFFORD ILKAY 10 Oct '09

10 Oct '09

Hello, I read a post <https://fedorahosted.org/pipermail/cobbler/2009-April/003838.html> that describes the same problem I'm having trying to install CentOS 5.3 via Cobbler. I created a CentOS 5.3 profile, mirrored a bunch of CentOS 5.3 repos, and the first problem I encountered was that the CentOS choked on the kickstart file that I've been using on Fedora 10 and 11. I removed lines from the file until it no longer complained. I got as far as the "Retrieving installation information" right after I selected the timezone and got an error: "Unable to read package metadata. This may be due to missing repodata directory. Please ensure that your install tree has been correctly generated. failure: repodata/primary.xml.gz from anaconda-base-2009-3211311.x86_64: [Errno 256] No more mirrors to try." I've run "cobbler sync" and "cobbler reposync" already. How do I work around this? -- Regards, Clifford Ilkay Dinamis 1419-3266 Yonge St. Toronto, ON Canada M4N 3P6 <http://dinamis.com> +1 416-410-3326

cobbler 2.0 webui profile list only shows 50 items
by Bryan Schneiders 02 Oct '09

02 Oct '09

I have more than 50 profiles. Only the first 50 are shown on the profile page. If I change how it's sorted I can see some of the hidden profiles. Is this intentional? Is there a "next page" button I'm not seeing? -- Bryan Schneiders bschneiders(a)woti.com 301-562-1900 ext 305

ksmeta and the webui
by Christopher Dale 01 Oct '09

01 Oct '09

I think I have stumbled into a small annoyance with the ksmeta field in the webui. I am using cobbler to build directory server and have the following ksmeta: suffix='dc=incommon, dc=dev' dsDBName=incommonDB adminDomain=incommon.dev configDirHost=ds01 rootDNPwd=incommon.dev adminPwd=password When I save (from the webui) the first time, I get the following result in the json file "ks_meta": {"suffix": "dc=incommon, dc=dev", "dsDBName": "incommonDB", "adminDomain": "incommon.dev", "configDirHost": "ds01", "rootDNPwd": "incommon.dev", "adminPwd": "password"} The webui is then refreshed with the following ksmeta line. Note that the single quotes have been removed. This also happens for double quotes. suffix=dc=incommon, dc=dev dsDBName=incommonDB adminDomain=incommon.dev configDirHost=ds01 rootDNPwd=incommon.dev adminPwd=password If I save from the webui again, the following transformation takes place in the json file "ks_meta": {"suffix": "dc=incommon,", "dsDBName": "incommonDB", "dc": "dev", "adminDomain": "incommon.dev", "configDirHost": "ds01", "rootDNPwd": "incommon.dev", "adminPwd": "password"} And the ksmeta field in the webui is rewritten in such a way as to separate the suffix. suffix=dc=incommon, dsDBName=incommonDB dc=dev adminDomain=incommon.dev configDirHost=ds01 rootDNPwd=incommon.dev adminPwd=password Please note that if I write the ksmeta line as such (no space between the parts of the suffix), everything is handled correctly. suffix=dc=incommon,dc=dev dsDBName=incommonDB adminDomain=incommon.dev configDirHost=ds01 rootDNPwd=incommon.dev adminPwd=password I realize that this is probably not a bug, per se, but if there is ever a real need to embed a space into the ksmeta, one would need to be mindful of the implications for the second time you save the profile.

cobbler 2.0 workaround for SELinux and misc issues
by Philippe Eveque 01 Oct '09

01 Oct '09

Hi, to share my testing experience with cobbler2.0 (thanks for it!) hoping it can hepls others. My context: - having one cobbler server1 being migrated from 1.6.x to 2.0. - having one cobbler server2 directly installed in 2.0 Both servers configured with ldap authentication in /etc/cobbler/[settings, modules.conf] authorization is also on in modules.conf [module = authz_ownership] Both servers are running with SELinux in enforcing mode. The cobbler 2.0 SW was built from the source in each case. I noticed the following: - on server2 set up from scratch cobbler import .... was complaining that the issued rsync command was failing I had to disable selinux for rsync to make cobbler import working with the following command. root# setsebool -P rsync_disable_trans=1 may be a better way exist ? or something to be notified by the cobbler check command ? Note this is not an issue is selinux is _not_ in enforcing mode. - on server1 (migrated from 1.6.x) and after migration: - Had to removed the "omapi" section from the /etc/cobbler/dhcp.template file a task for cobbler check ? (not sure but that helps dumb guy like myself not reading the docs... :-( ) - Some text comments attached with the systems had "accents"/diacritics char. I had to removed them (from jason files) to avoid a python stack trace in the new WEB interface (1.6.x was not having issue there - may be due to the move to django) - In the new WEB interface, I got python stack trace when trying to sort the "Systems" view on a per profile basis The pb was with the /usr/share/cobbler/session/sessionid..... file the following solved the issue: root# chcon -t httpd_sys_content_t /usr/share/cobbler/web/sessions and to be sure it will be persistent: root # /usr/sbin/semanage fcontext -a -t httpd_sys_content_t "/usr/share/cobbler/web(/.*)?" may be something that can be addressed at installation time ? Note this is not an issue is selinux is _not_ in enforcing mode. - The "owners" field is not displayed anymore in the web interface. That was very usefull to figure out who to contact. Any easy way to make it visible again ? Apart the small annoyance sabove, cobbler2.0 on server1 (the migrated one) works very well and I continue testing and experimenting with it. thanks, Phil.

Using usb disk cobbler boot and experiencing problems with initial menu/keyboard
by David Jablonski 30 Sep '09

30 Sep '09

I have built 5 other machines using the usb image I created using the cobbler buildiso and the usb-livecd commands. Unfortunately this particular machine currently will boot to the menu and then the keyboard doesn't work and it won't load the kernel image (even if I change the default to be the correct profile manually on the boot disk). It just starts to load the isolinux image and then goes right back to the menu. Has anyone experienced this before? Is this a module missing issue? The machine is a Dell Optiplex GX620. Unfortunately I don't see any errors... Also I can get a Koan LiveCD to boot fine. Can I use this to start the baremetal install process? This machine has brand new harddrives and koan has never been installed. I'm not sure how to use the Koan LiveCD to start the baremetal install process. Thanks for any advice... -- David W.

Hi all, Today i have rename a repo in cobbler. The rename works but all data of this repository has been deleted. Is it a normal behavior of "cobbler repo rename --name=myoldname --newname=mynewname" ? Thanks for your answers. Baptiste.
