There were two disks in sw-raid. There were /dev/md1
as swap, /dev/md2
as boot and a /dev/md3
with ext4
.
The sw-raid was disabled by stopping and removing mdadm
and then zeroing the superblock on each /dev/mdX
partition with:
sudo mdadm --zero-superblock /dev/sda1
sudo mdadm --zero-superblock /dev/sda2
sudo mdadm --zero-superblock /dev/sda3
In the disk that is the first boot device, I don't know if it's relevant, the system type of each partition was set back from fd
to 82
or 83
with fdisk
, /etc/fstab
was updated, changing /dev/mdX
to /dev/sdaX
, and grub
was reinstalled on the boot partition (/dev/sda2
) with grub-instal
. But the system wont boot.
What else should I do to use this disk as the boot device without reinstall or data loss?
Current output of fdisk
Device Boot Start End Blocks Id System
/dev/sda1 2048 33556480 16777216+ 82 Linux swap / Solaris

With it doesn't boot I mean that it stops in the grub console (with the grub>
symbol). A ls
command says:
(hd0) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1) (hd1) (hd1,msdos1)
It's weird because hd1 was formatted with ext4...
