The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

Configuring tmux

I recently switched over to neovim (see my screenshots at the bottom). Below is my updated config file.

It's currently synchronized with my .vimrc config except for a block of neovim-specific terminal key mappings.

This is still a work in progress (everyone's own config is always a labor of love), but I'm already extremely pleased with how well this is working for me with neovim. While terminal mode isn't enough to make me stop using tmux, it is quite good and I like having it since it simplifies my documentation workflow for yanking terminal output to paste in a markdown buffer.

These days I primarily develop in Go. I'm super thrilled and grateful for fatih/vim-go,

HP Smart Storage Admin CLI (`ssacli`) installation and usage on Proxmox PVE (6.x)

Why use HP Smart Storage Admin CLI?

You can use ssacli (smart storage administrator command line interface) tool to manage any of supported HP Smart Array Controllers in your Proxmox host without need to reboot your server to access Smart Storage Administrator in BIOS. That means no host downtime when managing your storage.

CLI is not as convenient as GUI interface provided by BIOS or desktop utilities, but still allows you to fully manage your controller, physical disks and logical drives on the fly with no Proxmox host downtime.

ssacli replaces older hpssacli, but shares the same syntax and adds support for newer servers and controllers.

Installation

iLO Remote Console

This small script lets you start iLO Java-based console from shell.

But why not HTML5?

iLO 2/3 doesn't have HTML5 console
Mounting local (from the client computer) ISOs is PAINFULLY slow via HTML5 client

TL;DR

If you just start it, it will ask you for everything:

	* Shows a message while asserting like:

	ok: [host] => {
	"msg": "disk usage 4.2B of total 20.0GB (21.0%) (should exceed limit 90.0%)"
	}

	* Note this only looks at first mount point on current node
	* Fails if disk is near-full
	* Last step pushes to a push-based monitoring service, which will alert us if it doesn't get there after some time
	* Need to setup a variable `disk_limit`, which is the max acceptable usage ratio, e.g. set it to 0.8 if you want to keep disks within 80% of max size
