【Hackintosh】macOS 下制作 OpenCore 引导 U 盘

制作 OpenCore 引导 U 盘

Setting up the installer

Now we’ll be formatting the USB to prep for OpenCore. We’ll want to use macOS Extended (HFS+) with a GUID partition map. This will create two partitions: the main MyVolume and a second called EFI which is used as a boot partition where your firmware will check for boot files.

Note: By default, Disk Utility only shows partitions – press Cmd/Win+2 to show all devices (alternatively you can press the View button)

【TrueNAS】使用 Node Exporter（Grafana）监控 TrueNAS

Situation

我们都知道，如果你知道在 TrueNAS OS 中通过 pkg 来安装软件，会得到下面的错误：

$ pkg install git
Updating local repository catalogue...
pkg: file:///usr/ports/packages/meta.txz: No such file or directory
repository local has no meta file, using default settings
pkg: file:///usr/ports/packages/packagesite.txz: No such file or directory
Unable to update repository local
Error updating repositories!

事实上，官方 doc 中有明确说到：我们不应该在 TrueNAS OS 中安装你想安装的软件，而是把这些软件安装在 Jail 里面。

问题来了，如果我想使用 Node Exporter 监控 TrueNAS 宿主机。

（实在是看不习惯 TrueNAS 自带的监控）

那么如果我把 Node Exporter 安装在 Jail instance里面，那么自然监控的是 Jail 本身，而不是 TrueNAS 宿主机。
