- Full disk encryption of internal laptop hdd (/dev/sda - uuid: ec6a4dbd-2fe0-423b-b832-8f3c0c0a0f83)
- Bootloader on a 256 MB partition on a usb-stick (/dev/sdb1 - uuid: 68d5916e-ea95-47b2-a5f8-fd767071c3f2)
Hardware:
- Laptop ThinkPad T61P - Intel Core 2 Duo T7700 @ 2.40GHz - 4GB RAM - HDD Sata 320GB
- USB-Stick LaCie iamaKey 4GB
Approach so far:
Using the sabayon 8 live dvd for amd64 and KDE (md5sum is fine) and the installation gui anaconda I configure the partition table as follows:
| Device | Size (MB) | Mount Point/RAID/Volume | Type | Formatting |
|---|---|---|---|---|
| LVM | ||||
| - vg_box | 305216 | |||
| -- lv_var | 6016 | /var | ext4 | OK |
| -- lv_root | 30016 | / | ext4 | OK |
| -- lv_home | 259168 | /home | ext4 | OK |
| -- lv_swap | 6016 | swap | OK | |
| -- lv_tmp | 4000 | /tmp | ext4 | OK |
| Harddrives | ||||
| - sda (/dev/sda) | ||||
| -- sda1 | 305244 | vg_box | physical volume (LVM) | ENCRYPTED |
| - sdb (/dev/sdb) | ||||
| -- sdb1 | 256 | /boot | ext4 | OK |
| -- free | 3599 |
When asked where the bootloader is to be installed I choose /dev/sdb1.
Installation works just fine and doesn't show any errors, but after rebooting and booting Grub off the usb-stick I get the following output:
error: no such device: 5671bade-970c-4b8b-a2f5-77e2429dd1c1
Entering rescue mode...
grub rescue>
What has to be done to get the intended setup working?
