+# sys-hlth-btrfs
+
+## Description
+Checks the health of all mounted Btrfs filesystems by inspecting device error counters.
+
+## Features
+- Iterates over every Btrfs filesystem.
+- Runs `btrfs device stats` and alerts if any error counters are non-zero.
+- Hooks into systemd and a timer for regular checks.
+- On failure, calls `sys-alm-compose.cymais@…` for notification.
+
+## Usage
+Just include this role in your playbook; it will:
+1. Deploy a small shell script under `{{ path_administrator_scripts }}/sys-hlth-btrfs/`.
+2. Install a `.service` and `.timer` unit.
+3. Send alerts via `sys-alm-compose` if any filesystem shows errors.
