In my case it seems that the ZFS command ignores the ashift and because the drives are reporting an insane physical sector size of 256KB, and ZFS goes for the maximum ashift of 64KB sector size despite me specifying the 4KB sector size. It appears the upstream OpenZFS project has already fixed these issues. They just need to be backported to Ubuntu. https://github.com/openzfs/zfs/commit/37f6845c6f86b1d04593e55d94318326006f4b5d My command: zpool create \ -o ashift=12 \ -o autotrim=on \ -o autoexpand=on \ -o autoreplace=on \ -O acltype=posixacl -O xattr=sa -O dnodesize=auto \ -O compression=zstd-3 \ -O normalization=formD \ -O recordsize=32k \ -O relatime=on \ pg \ mirror nvme0n1 nvme1n1 mirror nvme2n1 nvme3n1 mirror nvme4n1 nvme5n1 mirror nvme6n1 nvme7n1 mirror nvme8n1 nvme9n1 \ mirror nvme10n1 nvme11n1 mirror nvme12n1 nvme13n1 mirror nvme14n1 nvme15n1 mirror nvme16n1 nvme17n1 mirror nvme18n1 nvme19n1 \ mirror nvme20n1 nvme21n1 \ spare nvme22n1 nvme23n1 The resulting zpool status output: zpool status pool: pg state: ONLINE status: One or more devices are configured to use a non-native block size.
