Proxmox with LVM-thin and why we should use Trim/Discard

Excerpts from the Proxmox VE Administration Guide]

LVM normally allocates blocks when you create a volume. LVM thin pools instead allocates blocks when they are written. This behaviour is called thin-provisioning, because volumes can be much larger than physically available space.

8.10.2. Trim/Discard It is good practice to run fstrim (discard) regularly on VMs and containers. This releases data blocks that the filesystem isn’t using anymore. It reduces data usage and resource load. Most modern operating systems issue such discard commands to their disks regularly. You only need to ensure that the Virtual Machines enable the disk discard option.

// Amazon で使った金額の合計を出す奴
//
// 使い方: 
//   1. 全部コピーする (右上の Raw をクリックした先でやるのが楽)
//   2. Amazon の注文履歴ページ ( https://www.amazon.co.jp/gp/css/order-history/ ) を開く
//   3. F12 または 右クリ→要素の検証 とかで出てくる開発者ツールのコンソール (JavaScript REPL) にペースト
//   4. エンターで実行
//      (Firefox はなんか allow pasting とタイプしろみたいなことを言われるので従う)
//   5. しばらく待つと alert で合計金額を表示
//
