Raspberry Pi 4B 8GB に Raspberry Pi OS を入れて、OMV のサイトのスクリプトでインストール。
https://github.com/hannesd/omv-zfs-ras-nas
基本的なところはここ。
ホスト名は前のシステムとぶつかるので後で切り替えた。OMV 上でやったらエラーになったので raspi-config で書き換え。
System → Date & Time で、タイムゾーンは Asia/Tokyo に。ntp はひとまず NICT 。
Access Rights Management → User でアクセスする PC のユーザーを追加。
ZFS はこちらを参照 https://legacy.gitbook.com/book/chibiegg/how-to-zfs
2台の USB HDD にパーティションを作る。

System → Plugins で github の手順で作ったプラグインをアップロードしインストール。Storage に ZFS の項目がでてくる。
Services → SMB/CIFS の設定。とりあえず Enable にして Save と Apply 。
Shares を開いて Add 、Shared folder の右の＋、例えば Name は Books と入力、Device はプルダウンで tank/Books を選択、Path は Device の選択のあと自動的に Books とでた。これで Save 。戻った画面でも Save 。そして Apply 。
他も同様にいれる。
DLNA サーバーを入れる。System → Plugins で検索窓で dlna と入力して現れる minidlna を入れる。
Services → DNA を開き Enable にして Save 、Apply 。Shares を開いて、Add 、Shared Folder に対象のフォルダを選択して Save 、Apply 。
Web UI での作業はここまで。
munin-node を入れる。munin の server は他にいる。
$ sudo apt install munin-node $ sudo vi /etc/munin/munin-node.conf （allow でサーバーのアドレスを追加、hostname にドメイン付きで設定） $ sudo systemctl restart munin-node
ドメイン名に問題があったので、ルーターの local server と local domain を書き換え。
