Question

Azure serial console can't see Rocky linux boot process

Michael Xu (Nokia) 0

I want to operate on my Rocky linux boot process to get into emergency mode, but I do not see it in serial console. It only shows booting process after some modules are started.

How can I solve the problem?

Thank You for reaching out to Microsoft Q&A forum.

To perform boot process in Rocky Linux boot process, ensure the GRUB file is configured by checking the settings /etc/default/grub. https://docs.rockylinux.org/books/admin_guide/10-boot/

To operate the boot process into emergency mode, you can configure with systemd.unit=emergency.target

If you have any queries, please share in details and error with screenshots to investigate further.

Hi Michael Xu (Nokia) ,

In continuation to above, please try with below steps for more troubleshooting.

Interrupt your VM at the GRUB menu. Please follow this documentation for more information regarding interruption of grub process. https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/linux/kernel-related-boot-issues#bootingup-differentkernel-ASC

Now, edit the boot parameters, navigate to the end of the line by pressing ctrl+e and append the string at the end of line which is starting with linux "systemd.unit=emergency.target".

Thereafter, press ctrl + x to reboot into emergency mode.

Once you are in emergency mode, try to use command "journalctl -xb" to view the system logs.
