Description of problem: Version-Release number of selected component (if applicable): Due to a power hit, one EL 7 system shows grub errors and doesn't boot. I would like to preserve the existing partitions on this system, therefore I do not want to re-provision it. I am requesting a modification to the Satellite server's PXELinux global default provisioning template (or create a separate rescue template) so I may PXE boot this system to rescue mode and troubleshoot the boot issue. How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Ross, PXELinux "local boot" template managed by Satellite directly boots from local drive. It does read MBR record and hands over to OS boot loader. In other words, it is not possible to tell which entry you want to boot. Here are the relevant bits: https://github.com/theforeman/community-templates/blob/develop/provisioning_templates/PXELinux/pxelinux_default_local_boot.erb https://github.com/theforeman/community-templates/blob/develop/provisioning_templates/snippet/pxelinux_chainload.erb What you want is technically possible, but you would need to create separate partition with rescue kernel/initeramdisk and boot from that volume. In this case, this is not good candidate for shipping by default. I am going to close your request, feel free to reopen and provide more details how technically you would like this to work.
