I'm trying to install openSUSE 11.4 x64 on OCZ Revo X2 drive. there are some problems I cannot go through.

So drive setup is (as during installation):

/dev/sda - WD regular sata drive
with:
/dev/sda1 - NTFS
/dev/sda2 - NTFS
/dev/sda3 - extended
/dev/sda5 - swap
/dev/sda6 - older opensuse root
/dev/sda7 - older opensuse home
/dev/sdb - OCZ Vertex
/dev/sdb1 - Windows 7 (old) 100 MB reserved NTFS
/dev/sdb2 - Windows 7 (old)
/dev/mapper/sil_bhadeiccaiaf - Revo
/dev/mapper/sil_bhadeiccaiaf_part1 - Windows 7 (new)

Now I want to add:
/dev/mapper/sil_bhadeiccaiaf_part2 - /boot
/dev/mapper/sil_bhadeiccaiaf_part3 - extended
/dev/mapper/sil_bhadeiccaiaf_part5 - /
/dev/mapper/sil_bhadeiccaiaf_part6 - /home
/dev/mapper/sil_bhadeiccaiaf_part7 - swap (I want to get rid of any system from WD and leave it for data storage/backup only)

And when I continue with installation i get an error when installer tries to create raid sil_bhadeiccaiaf_part_3

System error: -1007

/usr/sbin/parted -s --align=optimal '/dev/mapper/sil_bhadeiccaiaf' unit cyl mkpart extended 17644 29187:
/usr/sbin/parted: invalid token: extended

Any ideas?
