[Bug 780198] Re: Cannot set bootable flag on md in text partitioner

[Frithjof Kuntze]

Perhaps the following link will help clarify this issue:

http://ubuntuforums.org/archive/index.php/t-1722471.html

Recently, I suffered with the same problem installing 10.4 on two 2Tb
drives in RAID 1 configuration.  Following the guidelines outlined in
the link above everything installed fine.

The highlights are:

1. Create a 1Mb BIOS boot partition one both drives (assuming RAID 1) but don't create RAID device on these partitions
2. Don't use/need a /boot partition
3. Don't worry about setting any partition to bootable
4. Create the rest of the partitioning scheme as always setting the physical device partitions to RAID.

There may still be a bug but in my case following these guidelines got
my system up and running with no problems.

Hope this helps.

Title:
  Cannot set bootable flag on md in text partitioner

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  Binary package hint: ubiquity

  During install from both 10.04 64 bit alternate cd and 11.04 64 bit
  DVD, text mode-  i cannot set a parition marked as 'raid' type to
  bootable.  When i press 'enter' it simply flickers but remains 'no'.

  Perhaps this has to do with metadata type?  It appears the metadata
  being used to create the partition is 1.2, where grub only currently
  supports .90 i believe.

  Expected:
  Select 'bootable' flag works on raid autodetect partition
  Selecting 'bootable' flag makes installer use metadata version .90 for this partition 
  If no parition is labled 'bootable', installer errors out and indicates you will not be able to boot.

  Or perhaps this is because 'parted' does not support both boot flag
  and raid flag simultaneously?
