I've had a chance to revisit this today. Part of the problem seems to be related to how the installer is seeing the 4k/4k disk.
The 4k/4k sector disk is 1TB in size, however, the partitioner only sees the disk as 125GB. The installer will partition this space and the installation will continue, but, we end up with an un-bootable machine. dmesg and syslog, however, see the full 1TB of space for the disk. If I run a df -h at the console during install time, we also see the correct sizes for the partitions (at least they seem to be): /dev/sdb1 761.7M 32.0K 761.7M 0% /target/boot/efi /dev/sdb2 73.2G 658.6M 68.8G 1% /target /dev/sdb4 807.9G 72.2M 766.8G 0% /target/home Also running parted in rescue mode, here's what we end up with: Model: SEAGATE ST91000640SS (scsi) Disk /dev/sdb: 1000GB Sector size (logical/physical): 4096B/4096B Partition Table: gpt Number Start End SIze File System Name Flags 1 1049KB 800MB 799MB boot 2 800MB 80.8GB 80.0GB 3 80.8GB 119GB 38.0GB 4 119GB 1000GB 881GB -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1065281 Title: Installer crashed when trying to partition 4k/4k sector hard disks To manage notifications about this bug go to: https://bugs.launchpad.net/dell-poweredge/+bug/1065281/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
