Public bug reported: When installing Ubuntu Server 13.10 (as well as 13.04, 12.10, and 12.04.{2,3}) on Advanced Format hard drives with native 4k/4k sectors, we encounter a crash in partman_server when electing to auto-partition using LVM. This also happens on the desktop versions.
Steps to reproduce: 1) Obtain a 4k/4k Advanced Format drive. 2) Begin installing Ubuntu Server 13.10. 3) At the partitioning phase select the "Guided - Use Entire Disk and Configure LVM" option. Actual Results: Once that is selected, the installer will try to partition the disk, but then it won't move past that point. If you switch over the Ctrl+Alt+F4 screen you'll see a segfault in parted_server. I've attached the crash dump from a recent attempt on the 13.10 desktp version. Expected Results: Successful auto-partitioning using LVM. Notes: Manual partitioning and auto-partitioning without LVM works fine. No crashes and the installer runs to completion. If no Advanced Format disk is available, this could possibly be replicated using qemu like so: qemu-system-x86_64 -enable-kvm -monitor stdio -m 1024 -bios /usr/share/ovmf/OVMF.fd -cdrom raring-mini-amd64.iso -global ide- drive.physical_block_size=4096 -global ide-drive.logical_block_size=4096 -drive file=t.img,if=ide,index=0,media=disk ** Affects: partman-basicfilesystems (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1215458 Title: Auto-partitioning with LVM on Advanced Format Disks causes parted_server segfault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/partman-basicfilesystems/+bug/1215458/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
