Updating a distro in cobbler

A few weeks ago RHEL 5.6 was released, the installation media was also updated. So it is time to get it into cobbler to deploy the latest dot release when provisioning new systems. Lets assume your profile name is rhel5-x86_64, you have an existing distro named rhel55-x86_64 and you want to replace it with rhel56-x86_64. Lets start with importing the new distro: # Mount the ISO as loop back mount /some/where/rhel-server-5.6-x86_64-dvd.iso /mnt/rhel56iso -o loop # Import the Install Media cobbler ….Read More

Some impressive figures about Spacewalk and my two cents

Today, I saw a interessing post on the spacewalk-devel mailing list. Lines of code Spacewalk has 2,908,841 lines of code, created in estimated 843 person years. This means 843 developers are needed to rewrite Spacewalk from scratch in one year! That’s amazing. Number of bugs fixed As stated in the post, the Spacewalk-team fixed 1012 bugs in the year 2010. Some 1061 bugs are still due to be solved, the Spacewalk-team will not running out of work in 2011. See ….Read More

Important RHN Satellite 5.4 bugs has been fixed

Red Hat recently released some bugfixes for the RHN-Satellite version 5.4. They needed approx. one month to develop a fix for those serious bugs. If you upgraded to sat540 before those bugsfixes have been released you will have a crippled database. The errata provides a way how to fix it. It needs some time, but it works perfectly. For “my” satellites it was taking about 48h for both satellites, about 12h for the master and 36h for the slave satellite. ….Read More

Pulp, what is it about it?

Thanks to Máirín’s posting I got aware of the Pulp project. What is it? I had a brief look at it, it is a Red Hat sponsored project with a similar functionality like Spacewalk and RHN Satellite. This brings me to the question: Is Pulp is intended to be a replacement of Spacewalk? It can make sense, it is written in Python as Cobbler is. Cobbler and Spacewalk are not really playing nice together. Spacewalk used Java, Perl and Python. ….Read More

It seems that lot of stuff is now working. As I promised, I’m going to examine whats working and whats not. I’ll file every single bug I’ll find, please do the same in a polite manner. First impression Installation and first sync of yum channels works like PostgreSQL support was there from the first ….Read More

RHN Satellite 5.4, first analysis

First of all: Where is the Red Hat Press release? Nada, nothing, nichts (yet)…. History As I wrote in my previous post, I’ll keep you posted with my latest findings. In another post, I was speculating about the upstream version. Now, Sat540 seems to be based on Spacewalk 1.2 which is not yet released. I was quite puzzled about that fact. Usually upstream (Fedora) projects are ahead of its commercial counterparts, this time it seems to be the other way ….Read More

Deploying RHEL as ESX guests – Kickstarting or using ESX templates?

Some time ago I asked my self the question if it is better to kickstart systems or working with ESX templates when deploying RHEL as ESX guests. I also had some discussions with friends working in the same industry. I tried it and came to the following conclusion: Kickstart the systems is the way to go. Pros: Kickstarted Systems are already up-to-date after installation. Proper SSH host keys. Using ESX templates ends up in having identical SSH host keys, from ….Read More
