Grub does not find ISO with more complex disk layout (separate /boot partition and LVM for root) #134

Closed Martin-Weiss closed 4 years ago

Martin-Weiss commented 5 years ago

We have an md0 for /boot and an md1 with lvm for the root filesystem.

/dev/md0 mounted to /boot with ext3 /dev/system/root (in LVM on md1) mounted to / with btrfs

In this scenario we get this error: grafik

I am not sure if/how often we might see such a problem but maybe this can be fixed some day.

Hmm, I guess our simple root_device setup might be wrong in this case. Before you rebooted can you please share the grub config file:

/boot/grub2/grub.cfg

Thanks.

Also the kexec based run_contained approach as documented here:

https://documentation.suse.com/suse-distribution-migration-system/1.0/single-html/distribution-migration-system/#_run_the_migration

Could be an alternative ?

@Martin-Weiss Is this still of interest ? If so could you provide the details I asked for ? Thanks

@schaefi - yes - AFAIK this problem still exists but unfortunately I do not have access to the original system anymore so can not provide the original grub.cfg. Probably we have to wait until I have the chance to reproduce during the next upgrade.

ok in this case I'm going to close this one and we take a look at it once there is an opportunity to access all data for debugging. Thanks
