I recently noticed that my primary ZFS array was at 78% capacity and ordered some larger disks. After replacing the first for six disks, zpool status reported it would take approximately 20 hours to resilver each of the 6 disks.

I wanted a way to keep an eye on the status, and more importantly, get a notification when each disk was complete so I could start the next one.

Having recently switched to Hyprland with Waybar, I decided to see what was possible for dynamic status and notification upon completion.

After a few minutes of investigation, here is what I came up with.

Using a Waybar Custom Module with a bash script and Pushbullet I was able to get dynamic updates in my status bar and receive a notification on my phone when the process completes.

Waybar config

    "custom/resilver": {
        "exec": "~/bin/resilver-status",
        "format": "{}"
    },

Bash Script

#!/usr/bin/env bash
while true; do
  ssh nil@pinky "zpool status tank -v | grep 'to go'"
  if [ $? -ne 0 ]; then
    echo "Resilver completed"
    ~/bin/pushover "Resilver complete!"
    break
  fi
  sleep 5
done

Pushbullet script

#!/usr/bin/env bash
MESSAGE="$1"
