Rescue system with RAID 0

[Darth9590]

Hello,

Booting into my previously working system, it only boots into GRUB. I have tried to restore or fix it, but I may have no idea what I am doing or maybe it's not fixable. One point of data, my 400W PSU failed 2 weeks ago and I upgraded it to an 800W Thermaltake, which I could boot into Debian fine. I am unsure if I had an HDD failure at this point.

My system is two 512 SSD that I made one logic drive in RAID 0. There is one other 125GB SSD that is just there for extra space. ls in GRUB shows

Code: Select all

(proc) (memdisk) (md/0) (hd0) (hd0,gpt1) (hd1) (hd1,gpt2) (hd1,gpt1) (hd2) (hd2,gpt2) (hd2,gpt1)

ls of (md/0) shows Filesystem type ext* - Last modification time 2024-11-15 21:55:39 Friday - Sector size 512B - Total size 997996544KiB
All other drives say No Known filesystem detected with ls.

I have tried this which resulted in error: attempt to read or write outside of disk 'hd0'.

Code: Select all

set root=(md/0)
linux /boot/vmlinuz-6.9.10+bpo-amd64 root=/dev/sda1
initrd /boot/initrd.img-6.9.10+bpo-amd64
error: attempt to read or write outside of disk 'hd0'.

I can see all my personal files by navigating (md/0). I am not sure how to proceed from aside a fresh install. Any advice on how I should proceed? Could this be a failing SSD that I should test? Thank you

Boot from live usb and run

Code: Select all

cat /proc/partitions

. Then run "file -sL" for each of the devices to give us a better understanding of your setup.

Ok so you have two raid devices. It seems they have been automatically detected and the raid is up and running as /dev/md127 with a valid filesystem. Maybe you want to

Code: Select all

fsck /dev/md127

next to check the filesystem?

Hello, I ran fsck, and looks like some errors were found. I am not sure if this is due to an improper shutdown, possible I lost power while the computer was asleep at work.

I guess sda1 could be where your /boot is stored? Can you

Code: Select all

mount /dev/sda1 /mnt && ls /mnt && umount /mnt

to verify this?

If that is the case then in GRUB this would be called (hd0,gpt1) and surely not (md/0)?

[Darth9590]

sda1 returned with lost and found folder, no boot. It was 102GB which shouldn't be my boot. sdc1 is 1GB and that contains /EFI/debian/ (grub.conf, .efi files). Should there be a boot folder in there?

I found the boot folder under the MD127 disk, which contains the vmlinuz, entire files, efi, and grub folders. Did I mess up my installation six months ago?
