Thanks for the patch, it appears to work perfectly so far. Do you have a name you'd like to use for the commit besides "Charlie Root" ? ---------------------------------------- Bug #2830: gpt(8) doesn't align partitions to 1MB blocks http://bugs.dragonflybsd.org/issues/2830#change-12825 * Author: ftigeot * Status: New * Priority: Normal * Assignee: * Category: * Target version: ---------------------------------------- The GPT partition scheme management utility, gpt(8) doesn't manage partition alignment at all. # gpt create /dev/da1 # gpt boot /dev/da1 # gpt show /dev/da1 start size index contents 0 1 - PMBR 1 1 - Pri GPT header 2 32 - Pri GPT table 34 2097152 0 GPT part - DragonFly Label32 We can see the just created boot partition starts on the legacy sector 34 offset, 17KB from the start of the device. 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. ---Files-------------------------------- 0001-Align-partitions-to-1MiB.patch (1.86 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.
