kernel panic not syncing vfs unable to mount root fs on unknown -block(0,0)

spupuz · 23. August 2022

i have a omv 6.0,

i cloned the boot disk from a tiny 32GB old SSD to a 500GB SSD with clonezilla

then wit gparted live i:

i removed extended partition for swap

i resized the boot partition

i recreated the extended and the swap

i got some problem because sometimes i got this error: kernel panic not syncing vfs unable to mount root fs on unknown -block(0,0) but not always.

now the system is running.

Any suggesttion in order to solve?

i can get now any log. ryecoaaron

ooooh cool i got it when i recreated the the swap partition it has changed the UUID.

now i changed it but i got this error:

Code

error: attempt to read or write outside of disk 'hd0'.

and this seems to be random too

Wolf2000 · 23. August 2022

My english is not good check out this page:

"attempt to read or write outside of disk hd0" - error | Linux.org

spupuz · 23. August 2022

seems not be related anyway i got still also the other error randomly.

this happen mostly if i do a reboot not if i start from a shutdown situation, can this be related to a motherboard bios firmware bug?

spupuz · 23. August 2022

can be related the size of the disk that is 500GB and the motherboard is an old Gigabyte? processo ir Q6660 core duo

ryecoaaron · 24. August 2022

No, the 500GB drive is not a problem. In addition to fixing the fstab, you need to run sudo update-grub

ok but i did only changed swap UUID not the root.

I did it but i'll try to reboot tomorrow morning since it's at my father house and he is gone to bed and i'm going too

ok but i did only changed swap UUID not the root.

That doesn't matter. But I did type the wrong command (had a few beers). I meant sudo update-initramfs -u. But it never hurts to run update-grub.

Code

root@openmediavault:~# sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-5.15.39-4-pve
W: initramfs-tools configuration sets RESUME=UUID=427783ac-a226-4431-93fd-e4cb0f5310d3
W: but no matching swap device is available.
I: The initramfs will attempt to resume from /dev/sdm5
I: (UUID=87e7014b-a734-4563-9b6c-01a9da1f58c3)
I: Set the RESUME variable to override this.

is it ok or what else do i have to do?

i should have solved in that way:
