There are two issues. The first is correct partition alignment, the second ashift value. In theory, I haven't tested this yet, manually creating the slices with a start position to sector 64 and using slices instead of whole disks for the zpool devices, and creating with an ashift of 12 may

I'm building a storage server with Dell MD1000 DAS and I just bought 30 drives with 4K sectors. One of the reasons I selected the new 4K sector is so I can easily find replacement drives 2-3 years from now when they start failing. Looks like this was a huge mistake. I'm fine if the drives report

As for using Advanced Format disks with 4K sectors in ZFS pools, the worst case scenario would be that these disks can be used in a backwards-compatible legacy 512 byte sector format but with slower r/w performance. Also, Hitachi provide a Windows utility to re-align 4k sectors on their

It probably won't help much. Any SATA controller should recognize the 4TB drives, and the problem with the drives lying about sector sizes won't be any better whatever controller you use. roy - Opprinnelig melding - maybe this might help:
