RH System Administration II: Chap 6: Managing Basic Storage Lab Managing Basic Storage Task 5

[doinita]

Hi,

In the Lab: Managing Basic Storage — Task 5, after I run systemctl reboot and try to SSH back to serverb, I am getting the error: "missing route to the host", and I am unable to SSH back.

Has anyone else experienced the same problem?

I would appreciate any help or suggestions.

Thank you.

Hi @doinita 

It is typical issue. You make some changes in /etc/fstab file, if something was done incorrectly it may be source of boot problem. One of next chapter ( Control the boot process/Repair File-system Issues at Boot ) describe the issue and way to solve in detail.  Simple solution for now is to reset serverb

Good luck

Hi @shura 

Yes, you were right — I must have misconfigured something in the /etc/fstab file.

And yes, I was happy to see in the next chapter that it’s possible to fix it by rebooting the server with systemd.unit=emergency.target.

Thank you once again for your help.

@doinita make sure you do :

1. systemctl daemon-reload

2. check the fstab entries working or not by running : #mount -a

3. then activate the swap : #swapon -a

4. verify the swap : #swapon --show

5. Then reboot.

If you can't login back then you need to troubleshooting using the emergency/ rescue shell.
