[Bug 191119] Re: Installer corrupts raid drive

[Phillip Susi]

Yes, it has been at least as far back as 9.04, I thought all the way
back to 8.04, but I could be mistaken.

Title:
  Installer corrupts raid drive

Status in “parted” package in Ubuntu:
  Expired

Bug description:
  Boot from standard 8.04 Desktop CD.
  Run installer, select default language, keyboard to get to Partitioner.
  Select Manual install
    Note that raid drives from booting windows are listed separately.
    Select partition on alternate, non raid, drive to install Ubuntu on.
  Edit partition and set mount point to "/"
  Set login, computer name, etc. and install.
  Reboot computer.
    Note that BIOS now shows first drive as not a raid member.
  Run Windows.
    Note that software needs to rebuild RAID 1 mirror.
  Reboot computer.
    Note that BIOS shows first drive as valid raid member again.

  The problem I have is that because Ubuntu doesn't recognize the RAID
  drives, it corrupts one of them when it installs the default boot
  loader. To even figure out that the installer is doing this I need to
  look in the advanced settings.

  It would help to have a complete list of all disk operations that will
  be performed (and the affected drives or partitions) clearly shown on
  the the final Ready to Install screen.

  Another solution would be for Ubuntu to better support the Intel ICH9R
  controller that I happen to be using, but I think that is only a
  partial solution because the next software raid system that Intel
  comes up with might not be supported (and I think that adding better
  support for Intel raid is already on the wishlist).
