Wondering how I can force ashift=12 on a new pool. The disks are 512b disks so it keeps building with ashift=9. I tried using sysctl vfs.zfs.min_auto_ashift=12 with no change. Thanks
The FreeNAS default ashift is 12, however if your drives have a 512byte sectors then it'll default to ashift 9. The ashift set is correct in this case.
Right but if i ever have a disk failure (likely) then it would likely get swapped with a 4k sector drive, that being the case I was under the impression it would be wiser to have the pool set ashift=12
