Hi OpenSuSE MicroOS Users,
I want to know how to rescue / reinstall grub bootloader.
The standard way of chroot and running grub-install does not work, because of the read-only filesystem.
MicroOS is designed in a way, that is on the one side very robust and it should not be necessary to boot a rescue system to repair it. But if it really breaks, it's much easier and faster to redeploy it then to try to fix it. Since I really run only container on my server with MicroOS, I only need to enable the containers again, that's all.
I booted the system over CDROM with OpenSuSE MicroOS Rescue Mode, but for me it's totally impossible to rewrite the bootloader to MBR.
transactional-update bootloader does also not work, because it can not write anything to /var/run
If transcational-update bootloader does not work anymore for you, then there is something more serious broken on your system. Before you spend hours on trying to find all the pieces which seems to be broken on your system, redeploy it.
Can maybe someone explain how to rescue systems, e.g. when you created an Image over Harvester and want to boot this system image?
With MicroOS we don't rescue systems, we re-install them.
I don't find a lot of infos at the web about how to rescue systems at opensuse microOS and it will be really helpful - if someone can support me in this Topic.
Because, as written, it's faster to re-install MicroOS then to try to repair it ;) Thorsten
Thanks a lot Have a lot of Fun.
Kind regards Torsten
