OpenBSD FDE key-disk Install on APU2C4
Dear community,
I'm getting confused with how to install OpenBSD on an pcengines APU2C4 board with FDE using a key-disk. When I'm following the official documentation for the full-disk-encryption, I'll end up with a broken installation after rebooting the system. The error message says that no active partition can be found on the SSD onto which I installed the encrypted partition. Since I'm not witnessing any problems with an unencrypted install of OpenBSD on the same machine, I curious about the key-disk and how parameters need to be set. 1. How do I have to initialize the key-disk? The documentation doesn't state anything specific, so I initialize the key-disk with `fdisk -iy`. I'm not making use of GPT partitioning here. 2. Are there any changes necessary to the key-disk itself? The docs tell you to add a partition of 1MB, which I do with `disklabel -E sd1` and then `sd1> a a` and so on. Anything else to do here? I hope this is enough information for to provide me with an answer on how to tackle my issue. If not, I'm gonna post all steps from an unsuccessful round of installation here. Cheers Dennis |

Hi jggimi,
My steps are the following: 1. Initialize sd0 with Code:
MAKEDEV sd0 Code:
fdisk -iy Code:
disklabel -E sd0 2. Afterwards I initialize the key-disk with the same commands on sd1, create a RAID partition of 1MB on it. 3. Running Code:
bioctl -c C -k sd1a -l sd0a softraid0 Code:
MAKEDEV sd3 Code:
dd if=/dev/zero of=/dev/rsd3c bs=1m count=1 And after carefully writing out everything here, it's working.... LOL - Done |
