Comment 0 for bug 1012863

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.
