lvm: boot form logical volume (hard disk) ??

Recommended Posts

Hi all,

 

does anyone know how to boot from a locgical volume?

the volume group is located on a mbr-parted partition (/dev/sda5)

 

Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: dos Disk identifier: 0x00002074 Device Boot Start End Sectors Size Id Type /dev/sda1 2048 499711 497664 243M 82 Linux swap / Solaris /dev/sda2 501758 976771071 976269314 465.5G 5 Extended /dev/sda5 501760 976771071 976269312 465.5G 8e Linux LVM

I dont' dare to execute nand-sata-install 'cause it does recognize just the MBR-Partitions. It seems to me that it will overwrite the volume group.

Currently I'm running bananian from the disk.

Added an new root-lv "/dev/langate/root-new" and rsynced the root-fs from the sd-card to the new root-lv.

Patched /boot/boot.cmd, executed 'mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr'.

It doesn't function. I can't describe the error-messages right now further.

Check /etc/initramfs.conf and make sure the lvm capabilities are there and rebuild initramfs image.  Then you'll probably want to reference the volume by UUID rather than device path
