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

[Jeff Lane]

Public bug reported:

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.
