During Install my drives were not seen on the "Allocate Drive Space" dialog; however, they are seen when I run the alternate CD and answer "No" to the question about RAID information detected

[Bryan Aho]

1) You are using Ubuntu 10.10
                - the Maverick Meerkat - released in October 2010 and supported until April 2012.

2) i386 Desktop Installer

3) When I selected Install, and got to the Allocate Drive Space dialog, I expected to see my drives

4) Instead, my drives were not seen by the "Allocate Drive Space" dialog.

However, when I quit and booted to the live CD, my drives were seen.

5) Workaround: Install from the alternate CD, and when I get to the question about RAID information detected... should we load it? I answered "No", and I was able to see my drives.

Thank you for taking the time to report this bug and helping to make Ubuntu better. While we appreciate the difficulties you are facing, it would appear that the CD image (ISO file) you downloaded could be corrupt. There is an easy way to verify the integrity of the Ubuntu ISO files you download. Could you please visit https://help.ubuntu.com/community/HowToMD5SUM follow the instructions and report back as to whether or not the MD5SUM verified? Thanks in advance.

Hello
can you retest the release candidate that will came the next 30 sept.
thanks
Fabio

[Bryan Aho (virtualbry)]

Hi Fabio,

Sure! Did someone make a code change in the GUI installer's partioner?

If not, I can try to test the latest daily build so there will be more time to address before release.

Thanks,
Bryan

[Bryan Aho (virtualbry)]

ok, to be proactive with this, I went ahead and grabbed the latest daily build I could find for today (http://cdimage.ubuntu.com/daily-live/20100928/maverick-desktop-i386.iso), and reproduced the problem again.

This time, I captured a two minute video showing the bug in the installer partioner GUI, and then showing how gparted sees the drives just fine once the live CD boots. (Please see video, attached.)

Attached please find the device information for my PC. (Generated with the "System Testing" application under System | Administration)

[Bryan Aho (virtualbry)]

Hi Fabio,

I tested this with the x86 desktop RC from today as you requested, and the problem still happens.

Thanks for your assistance,
Bryan

[Fabio Marconi (fabiomarconi)]

Hello Bryan

Thanks for the support

Can you please run a live session, start the installation, go on till the partition manager, quit the installation and attach here:
/var/log/syslog

Thanks
Fabio

[Bryan Aho (virtualbry)]

Hi Fabio,

You're welcome! Thank you for your help! :)

Attached please find the syslog requested.

Cheers,
Bryan

[Fabio Marconi (fabiomarconi)]

Hello

From your syslog
Oct 2 00:55:36 ubuntu activate-dmraid: Serial ATA RAID disk(s) detected. If this was bad, boot with 'nodmraid'.
(is your disks a raid?).
If no then at the first screen press any key to activate the settings, select launguage, enter, press F6 and select with down arrow
nodmraid, enter, Esc, press back space till deleting -- quiet splash, enter two time.
It will start in textual mode
If you are able, verify that the jumper of you're HD is not setting it into RAID mode (if not, better don't touch).
Fabio

Hi Fabio,

Yes, my drive is configured as RAID-0, and attached to a "Silicon Image SiI 3132 SATALink Controller".

(The motherboard also has RAID and IDE support, but it is disabled since I have a RAID controller card.)

I booted with the nodmraid option as you suggested, and got the same result... no drives in the installer's partition manager.

Attached please find the syslog from that boot.

Thanks for your assistance.

--Bryan

P.S. I'm pretty sure this used to work fine in 7.x or 8.x, and since gparted sees the drives fine, I suspect this is a bug in the partition manager.

[Fabio Marconi (fabiomarconi)]

Hello
just to be clear, when you run the alternate cd and reply yes to the raid question it isn't showed and if you reply no they are showed ?
Thanks
Fabio

[Bryan Aho (virtualbry)]

Hi,

When I see the "Activate Serial ATA RAID devices" prompt on the alternate CD, and say "No", I am able to see the partition and configure the drives as expected.

However, when I answer "Yes", it can't see the partition.

(To make sure this was still an accurate test, I downloaded the alternate CD x86 RC just now and retested using it.)

Thanks,
Bryan

[Fabio Marconi (fabiomarconi)]

Ok
I assign the bug to partman-auto-raid and set it to new
Thanks again
Fabio

Having similar problem: i see only half of my drives in "Allocate Drive Space" dialog.

/dev/sda/ - raid disk, Gparted:visible, Installer GUI: invisible
/dev/sdb/ - standalone disk, Gparted:visible, Installer GUI: visible
/dev/sdc/ - standalone disk, Gparted:visible, Installer GUI: invisible
/dev/sdh/ - raid disk, Gparted:visible, Installer GUI: invisible
/dev/sdi/ - raid disk, Gparted:visible, Installer GUI: visible

Using: Ubuntu 10.10

Attaching my syslog too: may be it will help.
