Re: [opensuse] update-bootloader and thin-LVM

Hey,

I am having trouble reinstalling Grub2.

I am in a live session of Kubuntu. I used it to backup my LVM volumes, and then to recreate them using thin volumes. I've done this two times before without thin-provisioned volumes and never got a problem.

Now I get this error:

grub2-probe: error: disk `lvmid/URtZA3-OgVA-rFoA-xjlw-BOsX-iVMd-U5iWJy/2fa6lw-4f4q-c20g-0Ry8-t02S-CMry-iI6jed' not found.

Grub2 does not include support for thin volumes. So it sees reference to LV when scanning devices but cannot really access them. Someone will need to implement for them ...

grub2-probe: error: disk `lvmid/URtZA3-OgVA-rFoA-xjlw-BOsX-iVMd-U5iWJy/D3KfrU-0PNZ-Eaaj-bCkN-FrYE-fUQB-32NAOX' not found. grub2-probe: error: disk `lvmid/URtZA3-OgVA-rFoA-xjlw-BOsX-iVMd-U5iWJy/rQU1DV-UKKx-BSRd-id3l-4fl8-N3SH-n66W3A' not found.

The full output is:

Those 4.1.0 images are from Kubuntu, they mess up the grub configuration but that is not the issue now.

Removing the 4.1.0 also doesn't change the errors. I have regenerated also using mkinitrd.

The grub2-probe is referencing blkids that don't exist.

Even the LVM container ID is completely incorrect.

/dev/mapper/sda6_crypt: UUID="dl5QvM-u91H-fJ52-ob75-E3Ld-5vGT-gTKyD3" TYPE="LVM2_member"

I'm now trying to manually edit the existing grub.cfg and getting rid of all UUID references. If the config file is not faulty it should boot all my systems.

I had trouble generating a correct grub.cfg anyway. The presence of the Kubuntu files caused the generator to go haywire. All the generated entries were incorrect, except for the one that said "Kubuntu ....." which booted OpenSUSE using the OpenSUSE kernel/initrd and filesystem.

grub2-install finished correctly. Does anyone know where the errors come from?.
