2023年12月15日

Overview

TrueNAS Scale の Pool の設定項目について確認する。

Reference

Environment

TrueNAS Scale 23.10.0.1

Pool

ここでは利用可能なStorageをどのような構成にするのかについて設定する。

大きくは

  • データ用Storageの構成
  • 読み込み/書き込み速度を向上させるための構成

について設定する。

データ用Strorage構成では

  • Stripe
  • Mirror
  • RAIDZx
  • dRAIDx

の前提知識が必要である。

また、Storageは CPU や　Memory に比べて速度が遅い傾向があるため、この速度を向上するために

  • 読み込み速度向上技術
  • 書き込み速度向上技術

がある。

General Info

Name

Encryption

  • Unchecked / default

Allow non-unique serialed disks

  • Allow
  • Don’t Allow / default

Data

Normal VDEV type, used for primary storage operations. ZFS pools always have at least one DATA VDEV.

Layout

Select VDEV layout. This is the first step in setting up your VDEVs.

  • Stripe
  • Mirror
  • RAIDZ1
  • RAIDZ2
  • RAIDZ3
  • dRAID1
  • dRAID2
  • dRAID3

Disk Size

  • available local disks

Treat Disk Size as Minimum

If checked, disks of the selected size or larger will be used. If unchecked, only disks of the selected size will be used.

  • Unchecked

Width : Layout対象のDisk数

Advanced Options

Manual disk selection allows you to create VDEVs and add disks to those VDEVs individually.

Log (Optional)

ZFS LOG device that can improve speeds of synchronous writes. Optional write-cache that can be removed.
