If you have an OpenBSD running on (mostly) encrypted RAID1 partitions like I described in https://sven-seeberg.de/wp/?p=1018, the unattended system upgrade triggered by
sysupgrade will fail after rebooting into install mode. Without interaction, the system is stuck in a reboot loop. To continue with the upgrade process, follow these instructions:
- When the error message appears that the system cannot continue, hit Control + C to prevent the system from rebooting. You should now have a shell.
- Decrypt the softraid:
bioctl -c C -l /dev/sd3a softraid0
- Hit Control + D or type
The unattended upgrade should continue normally without any further interaction.
