if you want somewhat usable iops don't use raidz, or use _a lot of_ raidz vdevs. the more zfs can spread the load across multiple vdevs, the better it can perform. In terms of a single raidz vdev the overall performance of the pool is roughly the same as the slowest provider (disk) of that single vdev. Yes, IO is spread across all of the disks ストレージ領域を効率的に使用して最適なパフォーマンスを得ることができます。raidz-1 の場合、3台 (2+1) 5台 (4+1) 9台 (8+1) のディスクを使います。以下の例では最もシンプルな (2+1) のセットを使います。 仮想ハードドライブとして 2gb のファイルを3つ作成: However, with a bit of trickery, we can convert a pool with one mirrored vdev into a pool with one raidz1 vdev, without having an extra hard drive on hand. Summary. We're going to create a zfs raidz1 vdev with a virtual device. This will allow us to create the raidz1 vdev with 1 fewer physical hard drive than we really have. The raidz1 vdev type specifies a single-parity raidz group; the raidz2 vdev type specifies a double-parity raidz group; and the raidz3 vdev type specifies a triple-parity raidz group. The raidz vdev type is an alias for raidz1. A raidz group with N disks of size X with P parity disks can hold approximately (N-P)*X bytes and can withstand P The raidz1 vdev type specifies a single-parity raidz group; the raidz2 vdev type specifies a double-parity raidz group; and the raidz3 vdev type specifies a triple-parity raidz group.
