[DragonFlyBSD - Bug #2674] GPT Support
Issue #2674 has been updated by ftigeot. Related to Bug #2830: gpt(8) doesn't align partitions to 1MB blocks added Bug #2674: GPT Support http://bugs.dragonflybsd.org/issues/2674#change-12686 * Author: ftigeot * Status: New * Priority: Normal * Assignee: * Category: * Target version: DragonFly currently doesn't have any GPT support in its installer, which makes it hard to install on 2TB storage volumes. Proposed roadmap: 1. Register some GUID partition types UFS and swap partitions could reuse the FreeBSD UFS and partition types New types are needed for HAMMER and HAMMER2 file systems 2. Add full-volume support to the installer The installer should be able to install DragonFly on a dedicated volume 3. Add partial volume support to the installer For people wanting to keep non-DragonFly managed data on part of a volume -- You have received this notification because you have either subscribed to it, or are involved in it.

Issue #2830 has been updated by ftigeot.

This isn't divisible by the physical sector size of modern disk devices (4KB). It isn't optimal with SSD either: they typically use 8KB or bigger erase blocks. gpt(8) should behave in the same as disklabel64 and align partitions to 1MB boundaries. -- You have received this notification because you have either subscribed to it, or are involved in it.
