Motivation

Main NAS は TrueNAS Scale を使っている
Backup NAS は、仮で Ubuntu+mdadm を入れている
- 運用は Zabbix を使って監視しようかと思っていたが、他にやりたいことが出てきたので面倒になった
Backup NAS も TrueNAS にしても良かったが、慣れた同じ TrueNAS にするのも面白くない
- (TrueNAS にすると Replication を TrueNAS の責任で行わせられるので楽ではある)
- Rockstor は知っていたので、とりあえず使ってみる

What is Rockstor

https://rockstor.com/
TrueNAS のような NAS 用 OS の仲間
ファイルシステムは Brtfs
- TrueNAS は OpenZFS
ベースとなる OS は、古くは CentOS、最近は OpenSUSE になっているらしい
- TrueNAS は FreeBSD/Debian
TrueNAS より HW 要件が緩い
- Raspberry Pi 4 も公式にサポートされている
ただし、Stable Channel で Update を受けるためにはサブスクが必要 (24EUR)
- https://opencollective.com/the-rockstor-project
- https://rockstor.com/docs/interface/system/update_channels.html#stable-channel

HW

今回は、じゃんぱらで安く入手した Dell Wyse5070 を使う

Install

https://rockstor.com/docs/installation/install.html

Configuration

Disk 初期化

左メニュー or 右上のメニューの STORAGE > Disks を選択
必要なディスクの歯車マークをクリック
Select Partition to use (filesystem) で Whole Disk (None) - active を選択

エラーが出たら SSH で接続して強制的にフォーマットする

SSH は root ユーザで行う
