CentOS mirror supplying bad pxelinux images

Post by trinaryouroboros » 2019/04/15 16:52:47

We are seeing a problem where the xfs module will not load during kickstart anaconda boot of PXElinux images downloaded from CentOS repo.

Issue is as described in: https://access.redhat.com/solutions/697913

Mirror retrieval for:
/centos/7/os/x86_64/images/pxeboot/initrd.img
/centos/7/os/x86_64/images/pxeboot/vmlinuz

Listing /boot:
initramfs-3.10.0-693.el7.x86_64.img
vmlinuz-3.10.0-957.el7.x86_64

According to support, it appears that these different versions may break functionality.

Your diagnosis is incorrect.

The current CentOS 7 version is 7.6 and uses a kernel 3.10.0-957.el7.x86_64. The current initrd.img from the current 7.6 DVD is also 3.10.0-957.el7.x86_64. These match and are correct.

If you are getting an initramfs containing 3.10.0-693.el7.x86_64 then you are picking up one from CentOS 7.4 which has not been current for over a year.

Check where you are getting your wrong copy of that initd.img. The one on the DVD is correct. I've also gone to http://mirror.centos.org/centos-7/7.6.1 ... s/pxeboot/ and downloaded the current initrd.img from there and it too is also correct and contains modules for the 3.10.0-957.el7.x86_64 kernel.

The incorrect file is coming from somewhere other than CentOS.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

Thank you very much for your help!

I ran the same thing today and the versions match and xfs module loads properly.

As much as I'd love a real root cause, I think I'll just let this go as some type of caching thing.
