Bug ID: 200641
Summary: FreeBSD 10.1 doesn't support 4K bytes sector for NVMe
Product: Base System
Version: 10.1-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
FreeBSD 10.1 fails operating system installation if the NVMe device doesn't
support 512 bytes sector size.
For NVMe devices, 4K sector size is typical for high performance applications.
Although some NVMe also support 512 bytes by default, many of them support 4K
sector sizes also. I tested and collected traces to show this is the case.
If FreeBSD is going mainstream for high performance applications, please add 4K
sector size support in the next FreeBSD version.
