Red Hat System Administration II Chap.10: Controlling the Boot Process Section 10.4 Exercise

[doinita]

Hi,

I followed the steps from Exercise 10.4:

• SSH to servera

• Switched to root using sudo -i

• Pressed Ctrl + Alt + Del in the console keyboard and selected Restart

• Interrupted the boot process by pressing any key except Enter

• Appended rd.break at the end of the linux line

However, after this, the server stays on the message:

Probing EDD (edd=off to disable)... ok

It has been stuck there for more than 20 minutes, and I am unable to complete the lab exercise.

Has anyone else experienced this issue? I would appreciate any advice or suggestions.

Thank you in advance.

Since the console is frozen, try a hard reboot from the lab portal. 
To prevent it from happening again, don’t press keys too quickly after rebooting and let the GRUB screen appear fully before editing

Thank you, Tudor.

In this scenario, the GRUB menu doesn’t wait for too long, and I need to press a key very quickly in order to edit the current entry.

I’m not sure how to perform a hard reboot from the lab portal, as all I can see is this screen, and there are no options available for rebooting.

I would appreciate any help.

I needed to use the console of servera as mentioned in the exercise.
Since I had never used it before and had only worked with the terminal, I wasn’t exactly sure what was meant.
However, I’ve now completed the exercise, and it was easy!

Thank you so much for your help, Tudor.

Looks like our messages crossed—glad to hear you figured it out!

I think there’s a support channel where some tech wizards can help you out live. @Wasim_Raja  is the gatekeeper of the knowledge treasure. Master, please guide us on the next steps!

Thank you again, Tudor.

I really appreciate your support with my RHCSA exam preparation and will reach out if I have any other questions.

On the lab page, under the actions for the respective VM, you can either click Shutdown to gracefully shut down the virtual machine while preserving disk contents, or click Power Off to forcefully shut down the virtual machine, still preserving disk contents. I hope this screenshot helps clarify

@doinita apart from the technique explained by @TudorRaduta , ie , the VM actions menu from where you can shutdown or power off - there is another way to trigger a ctrl+alt+delete from the vnc console , attaching a screenshot.
