Zabbix applianceをVMware ESXi 6.7に導入してサーバ，ネットワーク機器の監視をはじめました｡
一通りの設定を終えてHDDの空き容量を見たら1.8GBでした｡

監視端末が少ないとは言え､さすがにこれでは1年も持たないのは見えているので新規HDDを追加しました｡
手順は下記の記事を参考にして下さい｡
- 仮想HDDの新規追加
- fdiskでLVMパーティションを作成
- 物理ボリューム(pv)を作成
- ボリュームグループ(vg)に追加
- 論理ボリューム(lv)の拡張
- ファイルシステムを拡張
- サイズの確認
ESXi 6.7のWeb Clientにログインして仮想マシンの編集を行います｡[ハードディスクの追加]から新規に50GBのディスクを追加しました｡
追加後に仮想マシンを起動､あるいは再起動すると/dev/sdbとして認識します｡

これで暫くは大丈夫かな｡
