Assumes you run Traefik.

You need to checkout the repository so you can mount the server and client directories into the container.

git clone https://github.com/RobinLinus/snapdrop.git

Then modify docker-compose.yml and create templates/default.conf.template.

Summary

This is a script I made to check the health of the ZFS pools on my Ubuntu server and send a notification with a summary to a Discord server channel (see image of example notification below) I have made for my servers. I borrowed and modified some parts for the actual ZFS health check from this Gist. The script checks ZFS pools overall condition, capacity, errors and time since last scrub. If an issue is detected with a pool a role on the Discord channel is pinged.

This script is only tested on Ubuntu Server 20.04.

Instructions

Copy the two bash files to a Linux server with ZFS pools and modify as required based on distro/version. Fill inn the Discord variables in the discord-variables.sh file.

version_cmp()

Simple function to (properly) compare version strings in bash

The problem

You can not do alphabetic comparison:

start new:

tmux

start new with session name:

tmux new -s myname
