Configure separated GRUB to run Linux from LVM ddrescued device












0















I got new 120GB SSD and I want to restore my Linux Mint from my ddrescued /dev/mapper/mint--vg-root



I splited SSD to 500MB sdb1 Ext4 and 119GB sdb2 LVM as it was before crash.



Then I created mint-vg group and made root volume. Restored ddrescued Mint image to mint--vg-root.



Then I installed GRUB to mounted sdb1 with this:



sudo grub-install --root-directory=/media/user/mouted_sdb1 /dev/sdb


Now when I boot from SSD I get GRUB black screen
I tried how-rescue-non-booting-grub-2-Linux, but GRUB says, that my lvm partitition has unknown filesystem:



grub> ls (hd0,msdos <TAB>

Available partititions are

Partitition hd0,msdos1: Filesystem type ext* - Last modified .....

Partitition hd0,msdos2: No known filesystem detected - Partitition start at ....


I tried boot-repair with GUI. It lists my mapper/mint--vg-root, but after repair my mint not in list of systems. Mark mapper/mint--vg-root as default requires LiveCD.



Tried to:



insmod lvm


In grub console without result (still no known):



Tried this:



sudo grub-mkconfig -o grub.cfg


It says that /dev/mapper/mint--vg-root is found, but in grub.cfg is no record about this.



How make GRUB to load my Mint from lvm?



UPDATE:



Here some Boot Info Summary from my old system and from new. In new I have no "Extended partitition"

SOLVED with how-rescue-non-booting-grub-2-Linux with some modifications in GRUB console:

grub> linux (hd0,msdos1)/boot/vmlinuz-4.4.0-112-generic root=/dev/mapper/mint--vg-root
grub> initrd (hd0,msdos1)/boot/initrd.img-4.4.0-112-generic
grub> boot


After boot I ran boot-repair and it works now.

  • So you took an image of your old drive and copied it to the new one using dd?

  • Yes. I took image from /dev/mapper/mint--vg-root from old drive. Then put image to new prepared /dev/mapper/mint--vg-root. All with dd

SOLVED with how-rescue-non-booting-grub-2-Linux with some modifications in GRUB console:

Where (hd0,msdos1) is sdb1.

Also I fixed UUIDs in /etc/fstab, because my boot /folder is mounted from (hd0,msdos1) partitition. There are all files like vmlinuz... and initrd.img to boot properly.
