View Full Version : Ubuntu Server 16.04 - won't boot

November 30th, 2018, 12:28 AM
Hello -

I trying to recover a server, that was brought to me and isn't booting. I'm kind of stuck - not sure how to proceed, without destroying the data.

Server boots up, and instead of getting a grub menu or anyhting just has a black screen with a blinking cursor.

It's got 4 3 TB drives, in software raid (mdadm). This wasn't setup by me.

Ran the boot-repair iso, and was unable to apply any fixes, as the boot-repair app complained about "no network connection" when in fact there _is_ a network connection. So, I saved the output to pastebin:


If I uncheck the "check for network connectivity" option in the boot-repair tool - it just complains about some missing grub2 package.

I haven't done much with software raid (mdadm), so I am unclear where the /boot partition lives? Is it on the software raid? Or does it need to be a separate partition? If so, why does it seem like it's viewable across all 4 drives?

Ideally, I'd like to save the data. It's not my server, so I have to be careful.
