A lightweight NAS management UI written in Go — built for Linux and FreeBSD, designed to stay out of the way of a vanilla system.

No container runtime. No database. No Node.js. Just a single compiled binary, some Ansible playbooks, and a handful of static files.

Go 1.22+ Linux FreeBSD ZFS / OpenZFS no external Go deps stdlib only

features

pool overview ONLINE

Health badges, usage bars, fragmentation, dedup ratio, and the full vdev tree per pool.

I/O statistics live

Read/write IOPS and bandwidth per pool — pushed via Server-Sent Events every 10 s. Falls back to REST polling.

dataset browser filesystem

Collapsible depth-indented tree. Compression, quota, mountpoint. Inline editing of any ZFS property.

snapshots snapshot

List, create (with recursive option), and delete snapshots — all with styled confirm dialogs. Page darkens and a live spinner appears immediately when any write operation runs.

user management users

Create, edit shell/password/groups, and delete local users. System accounts (uid < 1000) hidden by default — toggle to reveal.

group management groups

Create, edit (name, GID, members), and delete local groups. System groups hidden by default with the same toggle.

ACL management POSIX / NFSv4

View, add, and remove POSIX and NFSv4 ACL entries per dataset. One-click acltype enable. Recursive apply.

NFS sharing sharenfs

Enable, configure, and disable NFS sharing per dataset via the ZFS sharenfs property. Cross-platform (Linux & FreeBSD).

SMB sharing usershares

Samba usershares per dataset. Manage Samba users. One-click setup playbook that configures usershares, disables [homes], and enables PAM passthrough.

S.M.A.R.T. health smartctl

Temperature, power-on hours, reallocated sectors, pending sectors, and uncorrectable errors per drive.

system info sysinfo

Hostname, OS, kernel, CPU, uptime, load averages, and process stats. ZFS and dumpstore version in the header.

Prometheus metrics /metrics

Go runtime, HTTP request counters & latency histograms, and Ansible playbook run metrics out of the box.

why this exists

I run a Kobol Helios64 as my home NAS — a five-bay ARM board that deserves better than the software ecosystem currently offers it. The existing storage UIs I tried were either too heavy, too opinionated about the underlying distribution, or simply unmaintained. None of them gave me a clean, no-nonsense window into my ZFS pools without pulling in a container runtime, a database, or a Node.js server alongside them.

What I wanted was simple: observe and manage my storage from a browser, on a machine that stays as close to a vanilla Linux or FreeBSD installation as possible. No agents, no daemons-within-daemons, no frameworks that outlive their welcome. Just a single compiled binary, some Ansible playbooks, and a handful of static files.

If you run a Helios64, an old server, or any ZFS box where you care about what is actually installed on it, this might be the tool for you.

install

1

clone and install

git clone https://github.com/langerma/dumpstore.git
cd dumpstore
sudo ./install.sh

The script checks prerequisites, compiles the binary, copies everything to /usr/local/lib/dumpstore/, and registers the service — systemd on Linux, rc.d on FreeBSD.

2

open the UI

http://localhost:8080

The service starts automatically after install.

3

uninstall

sudo ./install.sh --uninstall

run without installing

go build -o dumpstore .
sudo ./dumpstore -addr :8080 -dir .

-dir must point to the directory containing playbooks/ and static/. Defaults to the directory of the executable.
