I have 2x 2TB 4K sector drives, joined with LVM to RAID-0. On top of that, I created an XFS, but that has sectsz=512. Will there be any real difference if I re-format with sectsz=4096? AFAIK, XFS will do I/O based on block size, so the sector size doesn't do any harm. Is that correct? A question for LVM: Is there anything I need to tell to LVM to let it know that those are 4K sector drives and I/O should be aligned to that? Drives are reported as 512b sectors, but really are 4K. There seems to be no way to instruct the kernel to see those drives as 4K drives. -- mit freundlichen Grüssen, Michael Monnerie, Ing.
