debian-installer lucid soft raid1+lvm2 incorrect part sizes and unable boot

[Alexey Maximov]

Binary package hint: debian-installer

so the problem is:

I have HP310 G5 (sata software raid in bios turned off)
im trying install ubuntu on softraid (mdadm) and as result I have 2 critical bugs (regressions since 8.04)

i did dd if=/dev/zero of=/dev/sdX bs=10M on both SATA disks before installation

my layout is simple, its /boot ext2 , / ext4 (lvm2), swap (lvm2)

and disk has parted to (both sata disks)
300M (for /boot) [raid0]
400G (lvm2 VolumeGroup1)[raid0]

1. after boot, i have lost my /boot, im expecting to get /dev/md0 but have /dev/md1p1 instead ?!?! with BROKEN raid for /boot. /dev/md1 with lvm2 works ok

2. in system log too many messages about incorrect partitions sizes and overlaps etc. this looks like installer make incorrect partitioning. when partitioning its produce sizes of partitions smaller ~1M and leave free space over md volumes, in 8.04 all ok here

NB: installation same way with 8.04 on same hardware step by step = 100% success, no problems

3. after install I unable to boot due to some plymouth or some other crap problems, cant detect why, but boot freezes.

Im ready to write simple video movie about this problem.

its a release critical problem. ( sadly. was tested with lucid current iso

[Alexey Maximov (amax)]

so installation md+lvm2 on servers was broken completely, should I try check it again with RC build ? is there any reasonable changes in this installer part ?

[Alexey Maximov (amax)]

Rechecked with latest snapshot.

same effect with soft raid 5 + lvm2 (my /boot on USB flash drive, my / on LVM2 over softraid5)

unable to boot and find / and lvm2 PV

not serious for production release and even LTS label.

NB. _same_ simple installation with 8.04 same way etc works OK, but 10.04 failed

can anyone check this bug, please?

[Alexey Maximov (amax)]

installed debian squeeze same way, bb ubuntu from this server. we need stable betas and releases.
