Bug #2496

CentOS deployment is not working. Kernel Panic on starting deploy machine
Description
Hi,
I have already asked in the irc channel but no one really had a clue what could be the cause for this. I have tried to deploy CentOS 6.2 and 6.4 on a virtual (VMWare) and a bare metal host. Both show a kernel panic on startup. Installing CentOS from CD works fine. I have done a fresh install of foreman 1.1 and compared the provisioning templates they are the same. Maybe something on my production install is messed up?

this sounds like a broken kernel / initrd, try removing the files from your tftp dir /tftpboot/boot/centos-..?
they would be auto fetched when toggling build.. if your mirror is slow, it might be that your machine will fetch the files prior to finishing the download, (only for the first time when you add the new os), so check that there are no more wget processes running on that machine.

Hi,
that's what I thought too. I have deleted the files under /var/lib/tftpboot/boot and changed to our local mirror. The kernel panic doesn't appear on the first boot, but on the first boot after the machine is deployed.
By the way the foreman-proxy log is always displaying an error for the download of the initrd and kernel:

thats odd, please do md5 checksum to validate

They are identical. :(

Hi,
can you confirm that this is not a bug and really a configuration problem on my end?
i.e. can you please try to deploy a centos 6.2 / 6.4 box?
Best Regards,
Oliver

I just built a CentOS 6.4 machine with no issues, using the default Foreman Kickstart. I used this mirror:
http://anorien.csc.warwick.ac.uk/mirrors/centos/$major.$minor/os/$arch
And my installer md5sums are:
1c7d04190b27858e1b8abc9866cf359f /var/lib/tftpboot/boot/Centos-6.4-x86_64-initrd.img e390e699cfbfcbf6603e7e80aaf40853 /var/lib/tftpboot/boot/Centos-6.4-x86_64-vmlinuz
So we have the same md5sums - what platform are you installing on? I was using a Libvirt KVM machine, for the record.

Hi,
thanks for testing.
I used a VMWare Vsphere 5.0 VM and a bare metal IBM eSeries x366.

Hi,
can you send me the contents of your partitioning template?
I just deployed on a third host and I saw some debug messages coming up... Maybe my partitioning template is wrong?

I have once more copy and pasted the prov template from a fresh install and now it works. :)
Sorry for the confusion.
