#434 Issue closed: [Debian testing]: /boot not correctly modified to boot after recovery¶
Labels: waiting for info, support / question
ypid opened issue at 2014-07-06 19:42:¶
Hi
I noticed that after a recovery from Debian testing the system was not
booting because it did not find it‘s root filesystem (changing UUID, new
btrfs filesystem). The problem can be easily fixed by booting with the
Debian installation CD in recover mode and either substitute the old
UUID with the new one or just run update-grub2. I tried both methods
on else untouched recovered systems successfully …
So I would suggest that rear chroot‘s into the recovered system and
tries to run update-grub2. What do you think?

Normally the UUID should be changed automatically. In which file did
you
need to change the UUID?

A search for my current UUID brings up the file /boot/grub/grub.cfg.

Should be easy to fix. See file usr/share/rear/finalize/GNU/Linux/15_migrate_disk_devices_layout.sh.

If it is a btrfs related fs then it is another script handling this (or not?). You could check the files:
./layout/prepare/GNU/Linux/13_include_filesystem_code.sh
./layout/save/GNU/Linux/23_filesystem_layout.sh
Perhaps, you'll find a clue in there? You should know that btrfs is still a moving target (development) and the commands might be different on other flavors of Linux.

might be related to issue #473

@ypid btrfs code has been enhanced in the meantime, so if you find the time try out rear-1.17.1.

I am afraid that currently I don’t find the time. To be honest, I am not using rear currently.

@ypid no problem then I just close the issue.
