Bug#422319: Buggy debian-installer of "etch" when using MD with encryption and LVM
Package: debian-installer
Version: Debian 4.0r0 network-CD or DVD1 "etch"
Hello,
when I setup following disc strukture:
/boot SWAP / /var /usr /home /misc
,--------, ,--------, ,--+--------+-------+-------+--------+--------+--, -----
| BOOT | | SWAP | | | ROOT | VAR | USR | HOME | MISC | | ^
`---*----´ `---*----´ | `--------+-------+-------+--------+--------´ | |
| | | | LVM
| | | LVM VG "SYSTEM" | |
| | | | |
,---*----, ,---*----, +------------------------------------------------+ -----
| md0 | | md1 | | md2 | raid1
`-*----*-´ `-*----*-´ `-------*---------------------*------------------´ -----
| | | | | |
| | | | | |
,-*--, | ,-*--, | ,----*-, |
|hda1| | |hda2| | | hda5 | | /dev/hda
`----´ | `----´ | `------´ |
,--*-, ,--*-, ,-*----,
|hdc1| |hdc2| | hdc5 | /dev/hdc
`----´ `----´ `------´
(DVD-ROM) /dev/hdd
the system starts up and all works fine. :-)
But when I setup following
/boot SWAP / /var /usr /home /misc
,--------, ,--------, ,--+--------+-------+-------+--------+--------+--, -----
| BOOT | | SWAP | | | ROOT | VAR | USR | HOME | MISC | | ^
`---*----´ `---*----´ | `--------+-------+-------+--------+--------´ | |
| | | | LVM
| | | LVM VG "SYSTEM" | |
| | | | |
| ,---*----, +------------------------------------------------+ -----
| |md1_cryp| | md2_crypt |
| | key | | Key | crypt
| | random | | Passphrase |
,---*----, +--------+ +------------------------------------------------+ -----
| md0 | | md1 | | md2 | raid1
`-*----*-´ `-*----*-´ `-------*---------------------*------------------´ -----
| | | | | |
| | | | | |
,-*--, | ,-*--, | ,----*-, |
|hda1| | |hda2| | | hda5 | | /dev/hda
`----´ | `----´ | `------´ |
,--*-, ,--*-, ,-*----,
|hdc1| |hdc2| | hdc5 | /dev/hdc
`----´ `----´ `------´
(DVD-ROM) /dev/hdd
the partitioner/installer say at the point when it setup SWAP:
---------------------------------------------------------------------------
The attempt to mount a file system with type swap in Encrypted volume
(md1_crypt) at none failed.
You may resume partitioning from the partitioning menu.
Do you want to resume partitioning?
<Go Back> <Yes> <NO>
---------------------------------------------------------------------------
so I try the followng (SWAP without MD-Device):
/boot SWAP / /var /usr /home /misc
,--------, ,--------, ,--+--------+-------+-------+--------+--------+--, -----
| BOOT | | SWAP | | | ROOT | VAR | USR | HOME | MISC | | ^
`---*----´ `---*----´ | `--------+-------+-------+--------+--------´ | |
| | | | LVM
| | | LVM VG "SYSTEM" | |
| | | | |
| ,---*----, +------------------------------------------------+ -----
| |hda2_cry| | md1_crypt |
| | key | | Key | crypt
| | random | | Passphrase |
,---*----, `---*----´ +------------------------------------------------+ -----
| md0 | | | md1 | raid1
`-*----*-´ | `-------*---------------------*------------------´ -----
| | | | |
| | | | |
,-*--, | ,-*--, ,----*-, |
|hda1| | |hda2| | hda5 | | /dev/hda
`----´ | `----´ `------´ |
,--*-, ,-*----,
|hdc1| | hdc5 | /dev/hdc
`----´ `------´
(DVD-ROM) /dev/hdd
I mean the partitioner/installer setups all correctly!
I install the software.
I install the GRUB for booting.
Then I reboot at the end.
But the output at boot time is following:
---------------------------------------------------------------------------
... start of the Kernel ...
...
Begin: Loading MD modules
md: md driver ...
md: bitmap Version 4.39
md raid1 personality registered for level 1

or missing modules, devices: cat /proc/modules ls /dev
ALERT! /dev/mapper/SYSTEM-ROOT does not exist. Dropping to a shell!

Enter 'help' for a list of built-in commands.
/bin/sh: can't access tty; job control turned off
(initramfs) _
---------------------------------------------------------------------------
initrd don't ask for the passphrase for md1_crypt :-(
Further I mean hda2_crypt are not initialiced with random key.
---------------------------------------------------------------------------
Now I install following strukture:
/boot SWAP / /var /usr /home /misc
,--------, ,--------, ,--+--------+-------+-------+--------+--------+--, -----
| BOOT | | SWAP | | | ROOT | VAR | USR | HOME | MISC | | ^
`---*----´ `---*----´ | `--------+-------+-------+--------+--------´ | |
| | | | LVM
| | | LVM VG "SYSTEM" | |
| | | | |
,---*----, .--------. +--------------+-+--------------+-+--------------+ -----
| md0 | | md1 | | md2 | | md3 | | md4 | raid1
`-*----*-´ `-*----*-´ `-----*---*----´ `-----*---*----´ `-----*---*----´ -----
| | | | | | | | | |
| | | | | | | | | |
,-*--, | ,-*--, | ,----*-, | ,----*-, | ,----*-, |
|hda1| | |hda2| | | hda5 | | | hda6 | | | hda7 | | /dev/hda
`----´ | `----´ | `------´ | `------´ | `------´ |
,--*-, ,--*-, ,----*-, ,----*-, ,----*-,
|hdc1| |hdc2| | hdc5 | | hdc6 | | hdc7 | /dev/hdc
`----´ `----´ `------´ `------´ `------´
(64MB) (1GB) (4GB) (4GB) (4GB)
(DVD-ROM) /dev/hdd
It works fine!
What I wish:
/boot SWAP / /var /usr /home /misc
,--------, ,--------, ,--+--------+-------+-------+--------+--------+--, -----
| BOOT | | SWAP | | | ROOT | VAR | USR | HOME | MISC | | ^

| md0 | | md1 | | md2 | | md3 | | md4 | raid1
`-*----*-´ `-*----*-´ `-----*---*----´ `-----*---*----´ `-----*---*----´ -----

,-*--, | ,-*--, | ,----*-, | ,----*-, | ,----*-, |
|hda1| | |hda2| | | hda5 | | | hda6 | | | hda7 | | /dev/hda

`----´ `----´ `------´ `------´ `------´
(64MB) (1GB) (4GB) (4GB) (4GB)
(DVD-ROM) /dev/hdd
Features:
SWAP encrypted (random key) and with a MD-Device.
More than one crypted MD-Devices for the LVM Volume Group "SYSTEM"
with different passphrases.
---------------------------------------------------------------------------
There is a further problem when hda have an error:
Then I must boot from hdc (in BIOS: HDD-2). But there ist no
grub installed and I don't know if the menu.lst ist korrekt for
booting from hdc (BIOS: HDD-2).
