MicroNAS

Lightweight web GUI to manage SMB shares, NFS exports, quotas, and users on a single home server (Proxmox LXC/VM). Runs directly on the host as a systemd service.

Proxmox LXC setup

Use a privileged Debian/Ubuntu container — required for the NFS server kernel module and quotas.

On the Proxmox host, load the NFS kernel module before starting the container:

modprobe nfsd
echo nfsd >> /etc/modules

Install

Run everything below inside the LXC container as root.

1. System dependencies

apt update
apt install -y git samba nfs-kernel-server quota python3 python3-venv

2. Clone the repo

git clone https://gitea.honeyy.duckdns.org/Honey/MicroNAS.git /opt/micronas

3. Python environment

python3 -m venv /opt/micronas/venv
/opt/micronas/venv/bin/pip install flask gunicorn

4. Credentials

cat > /etc/micronas.env <<EOF
MICRONAS_USER=admin
MICRONAS_PASS=changeme
EOF
chmod 600 /etc/micronas.env

5. systemd service

cp /opt/micronas/micronas.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable --now micronas

Open http://<lxc-ip>:5000 in your browser.

Quota setup (one-time, per filesystem)

Quotas are a filesystem feature — they must be enabled on the partition that holds your shares (usually /srv) before MicroNAS can set them.

Step 1 — Enable quota mount options

Edit /etc/fstab. Find the line for the partition that contains /srv and add usrquota:

# Example — your device path and options may differ
/dev/sdb1  /srv  ext4  defaults,usrquota  0 2

Remount to apply without rebooting:

mount -o remount /srv

Step 2 — Initialise quota database

quotacheck -ugm /srv
quotaon /srv

This creates /srv/aquota.user. You only need to run this once; quotaon is automatically called on boot via the quota init script.

Step 3 — Verify

repquota -u /srv

If it prints a header and user list (even if empty), quotas are active. MicroNAS reads this output for the dashboard.

Note: if /srv is not a separate partition (e.g. it lives on the root / filesystem), add usrquota to the / entry in fstab instead and run quotacheck/quotaon on /. The Quota button in MicroNAS detects the correct filesystem automatically via df.

Updates

cd /opt/micronas
git pull
systemctl restart micronas

Network

The service binds to 0.0.0.0:5000 — accessible from any LAN device at http://<lxc-ip>:5000.

For HTTPS, put nginx in front as a reverse proxy.

LAN or Tailscale only — never expose to the internet.

Dev / test

# Quick local run (no gunicorn needed):
MICRONAS_USER=admin MICRONAS_PASS=secret flask --app app.py run --debug --host=0.0.0.0

# Or with docker-compose (UI only — systemctl/samba calls won't work):
docker compose up

Auth

All routes require a login session. Go to http://<lxc-ip>:5000 — you will be redirected to the login page automatically. Credentials come from MICRONAS_USER / MICRONAS_PASS in /etc/micronas.env. If MICRONAS_PASS is not set the app starts unprotected and logs a warning — do not do this in production.
