    Dual boot with
    • Windows XP
    • Ubuntu 10.04 LTS x32

  • Hardware
    • Fake RAID 1 (mirroring) with 2x1 TB:

Partition 1 - Windows
Partition 2 - SWAP
Partition 3 - / (root)
Partition 4 - Extended
Partition 5 - /home
Partition 6 - /data

I want to upgrade from 10.04 x32 to 12.04 x64 using FRESH installation.

So, run installation of Ubuntu 12.04.1 x64 LTS using alternate CD.

During the installation I selected manual partitioning and to:
- Use and Format / (root)
- Use and Format SWAP
- Use and Keep data on /home
- Use and Keep data on /data


After I clicked "Continue" I get error creating and formatting SWAP partition.

I go to terminal with Alt + F2 (?) and hit enter.
I discovered that there was visible RAID as only disk with NO partitions.
Something like this:

arek@domek:/var/log/installer$ ls -l /dev/mapper/
lrwxrwxrwx 1 root root 7 Oct  7 20:17 /dev/mapper/pdc_jhjbcaha -> ../dm-0


arek@domek:/var/log/installer$ ls -l /dev/dm*
brw-rw---- 1 root disk 252, 0 Oct  7 20:17 /dev/dm-0



So I switched to log console Alt+F3 (?) and saw errors like below:

As You can see there are 2 errors

Oct  7 14:02:55 dmraid-activate: ERROR: Cannot retrieve RAID set information for pdc_jhjbcaha


and

Oct  7 14:06:11 partman: mkswap: can't open '/dev/mapper/pdc_jhjbcaha2': No such file or directory


I looked in the internet and try to run command "dmraid -ay" and get something like that:


dmraid -ay
/dev/mapper/pdc_jhjbcaha -> Already activated
/dev/mapper/pdc_jhjbcaha1 -> Successfully activated
/dev/mapper/pdc_jhjbcaha2 -> Successfully activated
/dev/mapper/pdc_jhjbcaha3 -> Successfully activated
/dev/mapper/pdc_jhjbcaha4 -> Successfully activated
/dev/mapper/pdc_jhjbcaha5 -> Successfully activated
/dev/mapper/pdc_jhjbcaha6 -> Successfully activated



Then I returned to installer with Alt+F1 (?) and click "Return" to return to partitioning menu. I did NOT change anything just selected again "Continue" and everything goes smoothly.

I hope this will help someone.

" Actually, it's not possible to setup a new ubuntu install with mdadm fakeraid (tried 12.04 and 12.10 alpha 2 alternate cd): only dmraid is offered." per:

https://lists.ubuntu.com/archives/foundations-bugs/2012-July/103906.html

https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/1028677

As of Oct 23, 2012 bug is still confirmed and un-fixed.
