What is a recommended XFS sector size for hybrid (512e) advanced format hard drives?

[Hillel Lubman]

Hi.

Looking around I saw some references that it's preferable to use sector size (sectsz) of 4 KB when creating XFS partitions on hybrid (512e) advanced format hard drives and also some mentions of making that a default in mkfs.xfs. However I noticed that my current mkfs.xfs (3.2.1) used with current Debian testing (Linux 3.16.0) still uses 512 B sectors by default.

Can you please clarify what after all is the recommended sector size for such drives and why isn't it a default in mkfs.xfs (since supposedly defaults are generally recommended optimal settings unless you have some special use case).

Can you please also add this topic to the XFS FAQ (http://www.xfs.org/index.php/XFS_FAQ[1]), since I couldn't find any information about it there.

Thanks!

Hillel Lubman.
