[Bug 1012863] Re: debian-installer unable to create 2.4TB partition

[Jeff Lane]

I should add that I CAN create 2TB partitions, as this is, IIRC, the
limit for msdos style partition tables.  My issue is that the installer
prevents me from completely partitioning this system due to the
inability to choose a partition table scheme other than msdos.

Title:
  debian-installer unable to create 2.4TB partition

Status in “debian-installer” package in Ubuntu:
  New

Bug description:
  On a server, I have three disks:

  /dev/cciss/c0d0 <- onboard RAID LUN of 146GB
  /dev/sda, /dev/sdb <- SAN LUNs of 2.4TB each

  I am attempting to install Ubuntu Server 10.04.4 on this machine.

  During partitioning, I elected to do manual partitioning.  I created a
  140GB root filesystem partition on the onboard RAID and also a 6GB
  swap partition on the RAID device.

  Next, I attempted to create a single 2.4GB partition on the first SAN
  device, /dev/sda.

  From the manual partiton summary screen in d-i, I chose sda. On the
  next screen I chose "Create a new partition".  On the next screen, the
  partition creation screen, I am told that the maxiumum size I can
  create is 2.4 TB.  So I create a single 2.4TB partition to be used to
  store data and hit Continue.

  This moves me to the Primary or Logical screen and I chose to make
  this a Primary partition.

  When I click Continue, I am brought to an Error screen that says the
  following:

  "partition length of 4683671552 sectors exceeds the msdos-partition-
  table-imposed maximum of 4294967295"

  Clicking continue here brings me back to the partition summary screen
  without my new partition.  I am not given the option at any point to
  use a different partition table layout that DOES support 2.4TB
  partitions.  As this is geared toward servers, and undoubtedly,
  servers have a very good chance of having more than 2TB of disk
  storage that need to be partitioned off, this is a big weakness in the
  Ubuntu Server installer.
