[RAID] Ubuntu 10.04.1 Install Partition Issues

In a terminal (Applications->Accessories->Terminal), type the following command:
      sudo parted -l
where "-l" is lowercase "L". This will display list of partition.
With Gparted, you could create:
   2GB partition for swap
   10GB partition ext4 ( to mount on "/")
   remaining space ext' ( to mount on "/home"
During install, you should be proposed manual partitioning.

For two last partition you can use ext3 instead of ext4.

Hello ,

Thanks a lot for your prompt reply on my question. As instructed I did use sudo parted -l and GParted to create
The desired partition.
When the job get done in GParted the following partition will appear and stay visible with the command
Sudo parted -l

1 /dev/sda4 Extended partition of 450 Gb

  /dev/sda5 LINUX SWAP 2 Gb
  /dev/sad6 ext4 29 Gb for future /
  /dev/sda7 ext3 250 Gb for future /home

remaining 178 Gb in this extended partition for future extension

When this partitioning get done / I did launch the Ubuntu installer and after the time zone definition screen
I found again the Partition screen empty and the installer stuck at that step with all options of the screen
Being grayed on. I was expecting to see the partition created by GParted at that step and was expecting to
Define in the install process the way to allocate the partition just created ?

Something is still incorrect in my setting but I have no idea what could be wrong here. I just know that at
Boot time the PC display some RAID configuration and settings but is should not affect the partitioning
If GParted works correctly ?

I get confused and really appreciate your precious comment .

Best regards Michel Thevoz

to quote the infamous words of someone on here:

1) did you check the md5sum?
2) did you burn the iso as slowly as possible?
3) did you check for defects in the burned cd/dvd?

1) To check MD5 of ISO image and after burned CD:
     https://help.ubuntu.com/community/HowToMD5SUM
2) Yes, Ubuntu installer (ubiquity) should ask you how you want to partition.
3) "Boot time the PC display some RAID configuration and settings": I never worked on a RAID configuration, but I know that in some case there were problems with RAID array with Lucid. Could you check in BIOS if RAID is activated.

Hello ,

Thanks for your willingness to help. I did check the Installer DVD and everything appears to be OK. I am convinced that our problem
Should be related to the RAID configuration of the ACEP inspire PC (Displayed at boot up time ).
For some reasons the standard install does not expect by default a RAID Array configuration and this is why it never come up to
the partitioning screen. It should be possible to use some special comments to workaround this problem but my knowledge here are
too limited to allow me to improvise !
I hope to find out in this forum someone who did practice that approach in more details..

Regards M. Thevoz

Hello ,

Thanks for your comments but the CD image is all good so far and that install issue seems to be related to the inability of the Ubuntu installer to deal with RAID configuration set up on this ACER Aspire PC.
I need to find out someone on the forum who get exposed to a LINUX install on a RAID Array PC.

Regards Michel Thevoz

I think you will have to convert question into a bug, to get more help.

I'm just starting to work on RAID issues, so I have not big knowledge on this domain.
Do you have a:
   true RAID configuration (with a dedicated hardware chip to do work)
   fake RAID (job done by CPU, with code in BIOS and OS)
   soft RAID (all job done in Ubuntu)
