cobbler-ext-nodes returning nil results for system with mgmt classes and parameters

by Matthew_Luettgen＠aotx.uscourts.gov

Greetings, Long time listener (false) first time caller (true.) I am experimenting with Puppet 3.0.1 and Cobbler 2.2.3. I created a test profile, a test sub profile, and a test system in cobbler (via the GUI.) When calling cobbler-ext-nodes hostname, I am getting nil values for both classes and parameters. Some facts have been obfuscated, any values that do not appear valid are likely obfuscated. All files are appears to be parsed by cobbler properly as there are no errors with 'cobbler sync.' [root@cobbler-test profiles.d]#cobbler-ext-nodes matt-test.domain.com classes: [] parameters: {} [root@cobbler-test systems.d]# cat matt-test.json { "boot_files": {}, "comment": "", "ctime": 1353957758.8682129, "depth": 3, "enable_gpxe": 0, "fetchable_files": {}, "gateway": "", "hostname": "matt-test.domain.com", "image": "", "interfaces": {}, "ipv6_autoconfiguration": false, "ipv6_default_device": "", "kernel_options": { "1": null }, "kernel_options_post": {}, "kickstart": "<<inherit>>", "ks_meta": {}, "ldap_enabled": false, "ldap_type": "authconfig", "mgmt_classes": [ "existing_class,BS_fake_class,BS_fake_class2" ], "mgmt_parameters": "<<inherit>>", "monit_enabled": false, "mtime": 1353958428.8554339, "name": "matt-test", "name_servers": [], "name_servers_search": [], "netboot_enabled": false, "owners": [ "admin" ], "power_address": "", "power_id": "", "power_pass": "", "power_type": "ipmitool", "power_user": "", "profile": "existing_working_with_other_systems_profile", "proxy": "<<inherit>>", "redhat_management_key": "<<inherit>>", "redhat_management_server": "<<inherit>>", "repos_enabled": false, "server": "<<inherit>>", "status": "production", "template_files": {}, "template_remote_kickstarts": 0, "uid": "MTM1Mzk1Nzc1OC44NzMyODY0MTEuM00000", "virt_auto_boot": 0, "virt_cpus": "<<inherit>>", "virt_disk_driver": "<<inherit>>", "virt_file_size": "<<inherit>>", "virt_path": "<<inherit>>", "virt_ram": "<<inherit>>", "virt_type": "xenpv" [root@cobbler-test profiles.d]# cat existing_working_with_other_systems_profile {"comment": "", "kickstart": "<<inherit>>", "name_servers_search": [], "ks_meta": {}, "kernel_options_post": {}, "repos": ["epel-5-noarch"], "redhat_management_key": "<<inherit>>", "virt_path": "<<inherit>>", "kernel_options": {}, "name_servers": [], "mtime": 1330096515.039284, "enable_gpxe": 0, "template_files": {}, "uid": "MTMyODIwNDM5Ni44MTI5NzgzNDAuOD00000", "virt_auto_boot": 0, "virt_cpus": 4, "mgmt_parameters": "<<inherit>>", "boot_files": {}, "mgmt_classes": ["base"], "distro": "<<inherit>>", "dhcp_tag": "<<inherit>>", "virt_bridge": "<<inherit>>", "parent": "rhel5u6-x86_64", "virt_type": "qemu", "proxy": "", "enable_menu": false, "fetchable_files": {}, "virt_file_size": 48, "ctime": 1328204396.81303, "virt_disk_driver": "raw", "owners": ["admin"], "name": "JENIE2", "virt_ram": 4096, "server": "<<inherit>>", "redhat_management_server": "<<inherit>>", "depth": 2, "template_remote_kickstarts": 0} Matt Luettgen

Quick fundraising update

by James Cammarata

Ok, so I'm breaking my self-imposed rule on this one to share some big news. The support from the community has only been increasing the closer we get to the close of the fundraising campaign, and it never ceases to amaze me. Greg DeKoenigsberg, now the Vice President of Community with Eucalyptus, announced that they would match all contributions up to $2000 to help push us to our target goal! Here's the official announcement on his blog: http://gregdekspeaks.wordpress.com/2012/11/20/shoes-for-the-cobblers-kids/ So a huge amount of thanks to the Eucalyptus team!

build reports no longer get sent after upgrade to 2.2.3

by Malantonio, John

Hello, I have upgraded to 2.2.3 from 2.2.1 and after the upgrade no longer receive build report emails as I once did, everything worked prior to the upgrade. I have made sure build_reporting_enabled is set to 1, also ran cobbler sync and restarted the cobblerd service. The server is able to send mail but the fact I don't even see any cobble attempts in maillog concerns me. Any suggestions?? -John

Re: [cobbler] cobbler 2.4.0, Fedora 17, eth0 and em1

by Zack Perry

For 2.4.0, the workflow documented in the cobbler man page doesn't work: Interfaces can be deleted using the --delete-interface option. Example: cobbler system edit --name=foo --interface=eth2 --delete-interface Actual session: [root@cobbler ~]# cobbler system report --name=nb2 Name : nb2 TFTP Boot Files : {} Comment : Enable gPXE? : 0 Fetchable Files : {} Gateway : 192.168.1.254 Hostname : nb2 Image : IPv6 Autoconfiguration : False IPv6 Default Device : Kernel Options : {} Kernel Options (Post Install) : {} Kickstart : <<inherit>> Kickstart Metadata : {} LDAP Enabled : False LDAP Management Type : authconfig Management Classes : [] Management Parameters : <<inherit>> Monit Enabled : False Name Servers : [] Name Servers Search Path : [] Netboot Enabled : True Owners : ['admin'] Power Management Address : Power Management ID : Power Management Password : Power Management Type : ipmitool Power Management Username : Profile : sl6-ph-x86_64 Proxy : <<inherit>> Red Hat Management Key : <<inherit>> Red Hat Management Server : <<inherit>> Repos Enabled : False Server Override : <<inherit>> Status : production Template Files : {} Virt Auto Boot : <<inherit>> Virt CPUs : <<inherit>> Virt Disk Driver Type : <<inherit>> Virt File Size(GB) : <<inherit>> Virt Path : <<inherit>> Virt RAM (MB) : <<inherit>> Virt Type : <<inherit>> Interface ===== : em1 Bonding Opts : Bridge Opts : DHCP Tag : DNS Name : nb2 Master Interface : Interface Type : IP Address : 192.168.1.12 IPv6 Address : IPv6 Default Gateway : IPv6 MTU : IPv6 Secondaries : [] IPv6 Static Routes : [] MAC Address : e8:9a:8f:17:1b:eb Management Interface : False MTU : Subnet Mask : 255.255.255.0 Static : True Static Routes : [] Virt Bridge : [root@cobbler ~]# cobbler system edit --name=nb2 --interface=em1 --delete-interface At least one interface needs to be defined. [root@cobbler ~]# IMHO, this should be considered as a bug. Regards, -- Zack

Is it possible to have system object inherits the 'Template Files' value from that of a profile's?

by Zack Perry

cobbler objects in general follow a very clear OO hierarchy. But the 'Template Files' attributes of profile and system objects seem to be exceptions to such a pattern. If the nodes that use the same profile share the same 'Template Files' attribute, it seems to be more economical to define the value of the attribute once in the shared profile, rather than doing so system by system? Am I missing anything here? Regards, --Zack

Re: [cobbler] cobbler 2.4.0, Fedora 17, eth0 and em1

by Zack Perry

Thanks Greg, > this has been discussed before and IIRC the theory is that the > scripts deal w/ whatever you name the interface when you add it to > the system. If you add an interface named 'em1' it would configure > and interface 'em1', just like for 'eth0'. I will review these network configuration related snippets more carefully, and then redo my tests. During my today's tests, for simplicity, I simply used a --kopts to disable the behavior. [...] Regards, -- Zack

cobbler 2.4.0, Fedora 17, eth0 and em1

by Zack Perry

I finally got around to test cobbler 2.4.0 from epel-testing to PXE boot Fedora 17. After the past few days struggles with Ubuntu, doing RH alike systems is like having a break :-) Nevertheless, I noticed that the system came up with em1. This is not news to me, and I know how to deal with it. But the Q is, up to now, the snippets bundled with cobbler 2.4.0 still assumes that the first network interface is named as eth0. What is the current plan in dealing this device name change (which I know quite a few people are not happy' with)? Regards, --Zack

Can 'Template Files' be in jinja2?

by Zack Perry

cobbler: 2.4.0 from epel-testing server: SL 6.3 64bit target: Ubuntu 12.04.1 LTS server Out of curiosity, I tried to use the jinja2 for a template file in /srv/cobbler/sources.j2 as follows: #template=jinja2 # # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. deb http://us.archive.ubuntu.com/ubuntu/ {{ os_version }} main restricted deb-src http://us.archive.ubuntu.com/ubuntu/ {{ os_version }} main restricted [...] In the system object, I have: Template Files : {'/srv/cobbler/sources.j2': '/etc/apt/sources.list'} The intention is to replace all lines in the /etc/apt/sources.list that have the local repo URL with the official ones. Note, this is done just for experiment. At work, we always use our own repo mirror. But, even with python-jinja2 installed on the cobbler server, I have been getting the following in the installed services.list: # ERROR: JINJA2 NOT AVAILABLE. Maybe you need to install python-jinja2? But, as evident from below, the cobbler host has it! [root@cobbler ~]# rpm -qi python-jinja2 Name : python-jinja2 Relocations: (not relocatable) Version : 2.2.1 Vendor: Dag Apt Repository, http://dag.wieers.com/apt/ Release : 1.el6.rf Build Date: Fri 23 Mar 2012 05:33:19 AM PDT Install Date: Mon 19 Nov 2012 09:34:01 AM PST Build Host: lisse.hasselt.wieers.com Group : Development/Languages Source RPM: python-jinja2-2.2.1-1.el6.rf.src.rpm Size : 2379618 License: BSD Signature : DSA/SHA1, Tue 03 Apr 2012 06:26:16 AM PDT, Key ID a20e52146b8d79e6 Packager : Dag Wieers <dag(a)wieers.com> URL : http://jinja.pocoo.org/ Summary : General purpose template engine Description : Jinja2 is a template engine written in pure Python. It provides a Django inspired non-XML syntax but supports inline expressions and an optional sandboxed environment. If you have any exposure to other text-based template languages, such as Smarty or Django, you should feel right at home with Jinja2. It's both designer and developer friendly by sticking to Python's principles and adding functionality useful for templating environments. Is it true that the jinja2 support is only available to snippets? That's my impression from reading /etc/cobbler/settings so far. Regards, -- Zack

Re: [cobbler] cobbler 2.4.0 and problems booting Ubuntu 12.10 desktop 64bit

by Zack Perry

Hi James, Thanks for your response. You meant what Jorgen said in http://www.mail-archive.com/cobbler@lists.fedorahosted.org/msg08100.html? quoted "downloading an daily cdrom image and use the kernel/initrd from that."? So far, I have consistent success using cobbler import loop mounted ubuntu-12.04.1-server-x86_64.iso without needing anything from the Ubuntu daily cdrom image site. I will try to PXE boot 12.04.1 alternative CD tomorrow evening. If I succeed again, I will test Fedora and RHEL. Once I am done with these, I will come back to 12.10. > That is a known issue with the x86_64 ISO currently available (date > of 10/17 I believe). I think Jorgen had a workaround that he shared > on the mailing list, beyond that it's broken on Ubuntu's end. Regards, -- Zack

cobbler 2.4.0 and problems booting Ubuntu 12.10 desktop 64bit

by Zack Perry

I have been testing 2.4.0 from epel-testing. So far, I have been successful in PXE booting Ubuntu-12.04.1-server, 64bit. Since I am off today, so this afternoon I decided to try to PXE boot Ubuntu 12.10 desktop. Setting up cobbler as usual, watching the initrd.gz and linux file retrieved successfully. Now, upon Download installer component, I got a window that displays: "The installer failed to download a file from the mirror. This may be a problem with your network, or with the mirror. You can choose to retry the download, select a different mirror, or cancel and choose another installation method. Downloading a file failed: Retry Change mirror Cancel Alt-F4 into the logging vt, I saw (manually transcribed): [...] Nov 15 23:13:34 choose-mirror[3541]: INFO: suite/codename set to: quantal/quantal Nov 15 23:13:34 choose-morror[3541]: DEBUG: command wget -q http://192.168.1.3:80/cblr/ks_mirror/ubuntu-12.10-desktop-x86_64/dists/qu... -O - | grep ^Architecture Nov 15 23:13:34 anna-install: Queueing udeb quantal-support for later installation Nov 15 23:13:34 main-menu[384]: DEBUG: resolver (libc-udeb): package doesn't exist (ignored) Nov 15 23:13:34 main-menu[384]: DEBUG: resolver (libnewt0.52): package doesn't exist (ignored) Nov 15 23:13:34 main-menu[384]: INFO: Menu item 'download-installer' seelected Nov 15 23:13:34 main-menu[384]: gpgv: Signature made Wed Oct 17 18:36:03 2012 UTC using DSA Kkey ID FBB75451 Nov 15 23:13:34 net-retriever: gpgv: Nov 15 23:13:34 net-retriever: Good signature from "Ubuntu CD Image Automatic Signing key <cdimage(a)ubuntu.com>" Nov 15 23:13:34 net-retriever: Nov 15 23:13:34 anna[3566]: cat: can't open '/tmp/net-retriever-3570-deduplicate/*': no such files or directory I double checked the cobbler server's Apache access_log and error_log, no clues so far. Would appreciate a hint or two as to how to go from here. Regards, -- Zack
