How To Set Up Software RAID1 On A Running LVM System (lenny)

[mccyberix]

Hello,
I have troubles setting up Software RAID1 On A Running LVM System (Lenny)
because my partitions are not according to the tutorial. My machine has two identical 500GB SATA drives and I configured one of them with the standard partition scheme (guided entire disk with LVM, not the encrypted option). The second one I leaved blank without any partition. Now comes my problem, according to the howto I should have the following partitions:

/dev/sda1 /boot

/dev/sda2 (extended)

/dev/sda5 (LVM)

but I have only:

/dev/sda1 /boot

/dev/sda2 (LVM)

...there is no extended partition, so when I do the setup with /sda2 instead of /sda5 everything goes well untill I come to the point "pvcreate /dev/md1"
where I get the error that I have to -ff this command. So please can you tell me why my debian installation woun't create the (extended) partition or how to get this done without this.

Thanks in advance!

I forget to tell you that my mdadm.conf shows up more arrays as it should, maybe thats ok but I'm affraid to have something messed up. here is my mdadm.conf

# mdadm.conf
#
# Please refer to mdadm.conf(5) for information about this file.
#

# by default, scan all partitions (/proc/partitions) for MD superblocks.
# alternatively, specify devices to scan, using wildcards if desired.
DEVICE partitions

# auto-create devices with Debian standard permissions
CREATE owner=root group=disk mode=0660 auto=yes

# automatically tag new arrays as belonging to the local system
HOMEHOST <system>

# instruct the monitoring daemon where to send mail alerts
MAILADDR root

# definitions of existing MD arrays
ARRAY /dev/md0 level=raid1 num-devices=2 UUID=7cbe93d1:c3548ceb:19d1a4dc:999fb1c2

You have to /dev/md0 devices in your mdadm.conf...

What are the outputs of

cat /proc/mdstat

and

fdisk -l

?
