Re: [cobbler] CentOS 7 install failure
by Chris Johnson
Hi,
Don't know if this last post made it.
I've narrowed it down to something in the network_config, pre and post
SNIPPETS. I have seen bug report 1117640 however no data is missing as
in that case, I've done a cobbler system getks and all the data is
there as far as I can tell. I pulled all three SNIPPETs out and
replaced them with the proper network kickstart line and the error about
an illegal IP address string is gone. The install has other issues but
that's not this problem.
So it's something in the network SNIPPETs that is causing the illegal IP
address string error when trying to install CentOS 7.

Cobbler on CentOS 7
by Harry Hoffman
Hi All,
Wondering if anyone is running cobblerd on CentOS 7? It seems that the
debmirror package isn't available and running cobbler check doesn't seem
to know what distribution it's running on, can't check httpd (even
though it's in the path
2 : Unknown distribution type, cannot check for running service cobblerd
3 : file /etc/xinetd.d/rsync does not exist
4 : Apache (httpd) is not installed and/or in path
5 : debmirror package is not installed, it will be required to manage
debian deployments and repositories
Thoughts?
Cheers,
Harry

named host records for IPMI addresses
by Jeremy Mordkoff
I am migrating to using cobbler to manage DNS
In my existing system, I have 2 DNS A records for each machine -- one for the main interface and one for the IPMI interface. Can I use cobbler to generate both?
At the moment I am letting cobbler generate the records for the main interface and I am manually adding the IPMI records.

exporting cobbler data
by Jeremy Mordkoff
I did google this. One post referenced a wiki article, but it was a dead link.
https://hosted.fedoraproject.org/projects/cobbler/wiki/MovingYourInstallT...
The second recommended using cobbler replicate, but that is failing with
running: rsync -avzH cobbler::cobbler-triggers /var/lib/cobbler/triggers
received on stdout:
received on stderr: rsync: safe_read failed to read 1 bytes [Receiver]: Connection reset by peer (104)
rsync error: error in rsync protocol data stream (code 12) at io.c(251) [Receiver=3.1.0]
rsync is running on the master but cobbler-triggers is not configured as a location
What is the best method to move my cobbler installation to a new server?

The physical box has only one network interface? If there are multiple
nw interfaces, make sure you are testing netboot with the same one you
tested with dhclient.
If you execute dhclient without specifying -s parameter (server IP
address), it also works?
Doing that will broadcast the DHCP request and that is what will be done
during netboot.

If the DHCP server is answering DHCP requests for other systems, the
baremetal system is in DHCP server
conf file, you do not see any DHCP requests from the baremetal system
during netboot at the DHCP server
and you are there are no other DHCP servers answering baremetal system's
DHCP requests, I can only assume
network issues. If there is an installed Linux OS in the baremetal
system, you could try running a DHCP
client (dhclient, dhcping, dhcpdump) in it to debug better.

Re: [cobbler] Ilo baremetal
by Uma Murali
Hi,
Thanks for your continued responses to this. If I remember correctly, I had
sent an email earlier stating that the issue with fence/ipmi was resolved,
when I identified the issue to be due to firewall.
I had some good progress with VM provisioning with cobbler, however seems
stuck with BareMetal provisioning, and here is the issue:
- No DHCP request received on the cobbler server in /var/log/messages, from
the baremetal
- The same cobbler server is serving up for VM DHCP without any issues and
there is evidence in /var/log/messages
- The cobbler server and the bare metal that I am trying is on the same
VLAN/subnet and there is no firewall between them
- It is also observed that the bare metal's dhcp broadcast is seen on
another dhcp server [using hp server automation], when trying to isolate
and identify the issue. At a time, we enable only one DHCP server on that
network. pxe is enabled on baremetal and on the console it is observed that
the server is trying DHCP broadcast
Can you please review and suggest what could be done here to resolve this
issue?
Thanks
Murali

Moving cobbler server from one network to another (and changing hostname)
by Will Dennis
Hi all,
I have a Cobbler (2.6.6) instance on a host that's currently connected to one network. It was a Cobbler testing system that has now proved its worth to us :) Now I'd like to promote it to the "production" Cobbler system at our site, and in doing that, would need to change the hostname (currently "cobbler-test") and also the network that it sites on (currently on our air-gapped test network, need to move it to a production VLAN.) How easy/hard is this, and what would I need to change in the Cobbler conf files (I'm assuming the hostname is a bigger issue... But maybe Cobbler embeds IP addresses as well?)
Thanks!

server crashes when trying reposync of centos6_x64_updates
by Joost Ringoot
Hello,
Since a week, my cobbler-server does a spontaneous reboot when I do a "cobbler reposync".
More specific when I do:
cobbler reposync --only="centos6_x64_updates"
It is still possible to install centos6 systems but they need the updates applied after install.
Information that could be usefull:
yum info cobbler.noarch | grep Version
Version : 2.6.3
yum info cobbler.noarch | grep Repo
Repo : installed
uname -r
2.6.32-504.12.2.el6.x86_64
I wanted to troubleshoot this with kdump, but the crash doesn't create a vmcore.
These commands however do give a crash and create a vmcore
echo 1 > /proc/sys/kernel/sysrq
echo c > /proc/sysrq-trigger
in a subdir of /var/crash
Any suggestions on how to troubleshoot this further are very welcome,
Thanks,
Joost
