I haven't read why Colin thought that's a misconfiguration on the system, but in my case, there has been no disk change, the system was installed and then, sometime later, upgraded, which is when the problem occurred. > Nobody brought it up to the release notes, so nothing was added. Of course, I can only suggest something after seeing a problem. I would suggest a text like this: If your system is configured to boot from a RAID array, eg. MDADM, you need to take extra precautions. After the upgrade procedure, but before the reboot, you need to manually ensure that GRUB is properly installed on all relevant disks. In the case of RAID1 (mirrored disks), do this: # lsblk sda... sdc... # or sdb You'll find the boot disks by their partitioning. For this example, it's sda and sdc. Then run these commands: # grub-install /dev/sda # grub-install /dev/sdc The other question is, why did this happen at all? I have previously upgraded other systems with the same RAID configuration (ie, RAID1 via mdadm), and can't remember having seen this problem. It would be better to actually fix the problem, if possible. Cheers, Toni
