Title:
preseed Lucid with RAID and LVM fails to
I've got the same problem using the standard netinstall image via pxe,
I've manually created a md0 for /boot and md1 for /.
After the first reboot, /boot wasn't mounted by ubuntu, and md1 got
assembled with /dev/sda and /dev/sdb instead of /dev/sda2 and /dev/sdb2.
This should be an high blocking
Attached is a working configuration for LVM + RAID partitioning.
Note that extended partitions must be used for the LVM physical device
(changing this to primary and using sd[ab]2 failed miserably). And also
note that you need to use LBA alignment either from a boot param
(preferred) or from the
OMG posted an older version... sorry about this.

preseed Lucid with RAID and LVM fails to boot
I believe this bug boils down to the disk being partition in the wrong
way by d-i. Take a look at this:
r...@zod[~]# cfdisk /dev/sdb
FATAL ERROR: Bad primary partition 1: Partition ends in the final partial cylind
Press any key to exit cfdisk
r...@zod[~]# fdisk -l
And sure enough, this bug report has the right solution in comment #3 :

Probably related to Bug #561573 and Bug #551965
Appending partman/alignment=cylinder as kernel boot parameter solved the
problem for me.

Finally! The solution for #2 is to do:
partman/alignment=cylinder
After this bootparam (in pxelinux.cfg/default), mdadm did the right
thing and the system booted just fine.
Note that this is done on 2 different x86_64 systems:
1. Sun workstation Ultra20 m2
2. HP xw4600
Both have 2 SATA disks
Pasi,
Thanks. I'm sure I had this option before. I tried that and it indeed
allowed the preseed to continue.
When done, I still see the /dev/md1p1 weird partitions and I get dropped
to initramfs shell to fix it manually. This sucks.
