Package: debian-installer
Version: Debian 4.0r0 DVD1 "etch"
Hello,
I can setup a crypted root filesystem when I select
the Partition table type "msdos". But then I can not
use the whole disk (2.3 TB).
The debian-installer/initramfs is buggy when I
use the "GUID Partition Table (GPT)" and I want to use
a crypted root filesystem. (Not with md!).
I can setup a running system with "gpt" when I setup an
uncrypted root filesystem (and then I can use the whole
2.3 TB).
-----------------------------------------------------
The details:
============
1. Hardware what I use
2. Preperation
3. What works! (First situation)
4. What NOT works! (Second situation)
5. Result
-----------------------------------------------------
1. Hardware what I use:
=======================
Motherboard with AMD-K7 (Sokel-A) 1 GHz.
1.3 GB RAM.
ICP Vortex RAID-Controller with
4 * 750 GB drives: In a RAID-5
configuration I have a drive with 2.3 TB.
The controller is used by the kernel module "gdth".
The Firmware in the controller is the newest.
In "etch" the version of the kernel driver "gdth"
is 3.05.
The producer "ICP vortex" tells me in an
email that I have to use the GUID Partition Table (GPT)
to use the full size of the Host Drive (/dev/sda).
The Kernel module "gdth" must be version >= 3.04 .
I have only a DVD-ROM on /dev/hdd. No other
drives (like /dev/hda, /dev/hdc or /dev/sdb ...).
>From /dev/hdd I boot the etch-DVD.
2. Preparation:
===============
Bevor the two situations which I describe
here I fill the begin of the Host drive
/dev/sda with zeros:
dd if=/dev/zero of=/dev/sda
(CTRL-C after 10 seconds)
3. What works! (First situation):
=================================
I start "etch" with expert modus.
At the "Partition method" I select "Manual".

+-----------------------------------------------------------------------+
In the following screen the debian installer give me per default
for the "Partition table type" the "gpt". That's the right choise but in this
first situation I select "msdos":

& &

In the following screens I setup the following disk structure:
/boot SWAP /
,--------, ,--------, ,--------,
| BOOT | | SWAP | | ROOT |
`---*----4 `---*----4 `----*---4
| | |

| | key | | Key |

| `---*------4 `-------*----4
| | |
| | |
,-*--, ,-*--, ,----*-,
|sda1| |sda2| | sda3 | /dev/sda
`----4 `----4 `------4
(Host drive of the ICP Vortex RAID controller)
remark: In a system for production I would setup a LVM over sda3_crypt
For testing I use only one Partition for "/".
In partman:

+-----------------------------------------------------------------------+
Restart the system:
-------------------
Grub works.
The bootup routine asks me for the Passphrase for sda3_crypt.
All work fine.

4. What NOT works! (Second situation):
======================================
Now I will use the GUID Partition Table (GPT).
At "Partition disks" I select "Manual"
+-----------------------& [!!] Partition disks +------------------------+
& &

& &
& <Go Back> &
& &
+--------------------------------------------------+
I select "gpt" for Partition table type.
...
In the following screens I setup the same like in the first situation:
/boot SWAP /
,--------, ,--------, ,--------,

`----' `----' `------'
(Host drive of the ICP Vortex RAID controller)
It shows in partman:

It it necessary to go through GRUB before select LILO !!!
I put the LILO in /dev/sda (in the MBR).

-----------------------------------------------------------------------------
5. Result:
==========
With a "msdos" Partition table type I can setup a crypted root-filesystem
all works well, but I can not use the whole disk size. :-/
With a "gpt" Partition table type I can setup a crypted root filesystem.
But at boot time initramfs fails. :-(
I can setup a running system with "gpt" when I setup an uncrypted root
filesystem.
