SOLVED - Error on boot: Kernal panic - not syncing: VFS - Works in GUI mode

[Muff]

Hi,

 

I noticed yesterday night that my GPU didn't show in the server and at the end I removed a bit of text in "Syslinux configuration".

I don't remember exactly what it was but it was something I saw from a SpaceInvader video before we could do the "PCI Devices and IOMMU  Groups" that's is currently exist under Tools > System Devices. It was something the app "Fix Common Problems" also complained about.

 

My Syslinux configuration looks like this now:

default menu.c32
menu title Lime Technology, Inc.
prompt 0
timeout 50
label unRAID OS
  menu default
  kernel /bzimage
  initrd=/bzroot
label unRAID OS GUI Mode
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui
label unRAID OS Safe Mode (no plugins, no GUI)
  kernel /bzimage
  append initrd=/bzroot unraidsafemode
label unRAID OS GUI Safe Mode (no plugins)
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui unraidsafemode
label Memtest86+
  kernel /memtest

 

And I removed a part from "kernel" or "initrd" under "label unRAID OS".

 

And now I get this error:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block.

 

I can run the server in GUI mode white out any problem.

 

 

Any idé on how to fix this? 😅

 

Thank you!

Thank you!

Adding "root=sda" worked.

 

Before:

label unRAID OS
  menu default
  kernel /bzimage
  initrd=/bzroot

 

After/Now:

label unRAID OS
  menu default
  kernel /bzimage
  append initrd=/bzroot root=sda
