Tink vs Rockstor
Rockstor is a BTRFS NAS OS with shares and Rock-ons. That is not a mechanic. Tink installs in one command, watches the Linux host, explains what is wrong, and helps you fix it.
Rockstor watches the pool. Tink answers “why is this VPS sick?”
Accidental sysadmins land on Rockstor because BTRFS NAS looks like cheaper ops than TrueNAS. Then the guest volume fills, nginx dies, and the Web-UI still shows healthy — no pool match for host fill. A filling /var is a Tink warning; it is not a Rockstor job unless you scraped the Web-UI and watched it.
Tink is the other job: detect the issue on the machine, say why it happened in plain English, propose the command, and run it only after you approve. Keep using Rockstor if you already run BTRFS shares. Use Tink if you run Linux servers and want a mechanic.
| Feature | Tink | Rockstor |
|---|---|---|
| Setup time | 30 seconds (one curl | sh command) | Hours — openSUSE NAS, BTRFS pools, shares, Rock-ons, then a host that still has no mechanic after the Web-UI stays green |
| What you get | Working monitoring, diagnosis, and approved fixes | A BTRFS NAS OS plus snapshots and Rock-ons. Disk fill, nginx, Postgres, and certs stay your problem until you SSH into the guest or Web-UI |
| Pricing | Free (Scout) / $9 / $29 per machine per month | Hardware plus optional Rockstor subscription. You still pay the person who owns the pool after the last share stays up |
| Hidden costs | None — fully managed | A quiet pool at 2am, BTRFS warnings that are not guest fill, and a second tool to tell you the Linux VM is sick while the Web-UI still shows healthy |
| Monitoring approach | Agent on the server — CPU, disk, services, logs, certs, ports | Pools, shares, snapshots, and Rock-ons. Rockstor does not watch a quiet cert or guest auth.log after the last Docker Rock-on started |
| Configuration | None after install — heuristics and AI | Pools, RAID profiles, shares, snapshots, Rock-ons, and which Web-UI warning actually pages you |
| Plain-English diagnosis | Yes — AI explains root cause, impact, and fix | You read the Web-UI, then SSH into the guest to change the Linux box the NAS already sits under |
| Fix execution | Proposes and executes approved commands with an audit trail | Start and stop Rock-ons and shares — Rockstor cannot free guest disk, rotate a cert, or stop SSH brute-force unless you wrote that task |
| Alerting | Built-in across 8 channels | Not a Rockstor job — Web-UI email plus a separate monitoring tool have to fire |
| Predictive alerts | Yes — disk fills in ~6 days, memory and CPU trends | Not a Rockstor job — a green BTRFS pool does not forecast a quiet guest filling up |
| SSH brute-force detection | Built-in — parses auth.log every scan | Never — Rockstor does not read guest auth.log, journald, or firewall state after the VM started |
| Machine offline detection | Agent presence monitoring with multi-channel alerts | Silence if the guest dies after the last Web-UI poll — unless you built a separate uptime check |
| Public status page | Shareable URL with 90-day history | None — Rockstor has no customer-facing status page for the Linux guest |
| Weekly fleet digest | Automated Monday digest + daily brief when issues are open | None — a pool recap is not a plain-English fleet narrative |
| On-call tracking | Built-in /oncall command + incident acknowledgment | Not included — wire failed Rock-ons into PagerDuty or another incident tool |
| Conversation interface | Telegram, WhatsApp, web dashboard, CLI | Web-UI and SSH. No mechanic you text when /var filled and the last BTRFS pool still showed healthy |
| Learning curve | None — works after install | Steep — BTRFS RAID profiles, pools, shares, snapshots, Rock-ons, and which failure is the NAS vs the running guest |
| Best for | Freelancers, small teams, accidental sysadmins (1-50 Linux servers) | Homelabs that already run Rockstor for BTRFS shares and Rock-ons, not a sick-VPS mechanic |
When Rockstor is the right choice
Keep using Rockstor when you already want that exact job:
- A NAS box with BTRFS pools and snapshots — you need shares, Rock-ons, and copy-on-write, not a mechanic.
- An existing homelab NAS — Web-UI shares, Rock-ons, and snapshots matter more than guest nginx, certs, and SSH on a quiet VPS.
- An existing lab or nested setup — Rock-ons already start, the pool already ships, and someone owns the Rockstor box.
- Hosts that only page on pool or share death — you already run Web-UI email, not a sick-box SSH loop.
The real cost of “just watch the BTRFS pool stay healthy”
Rockstor runs storage and Rock-ons. A working ops loop for five Linux boxes is not:
- A healthy BTRFS pool still means you SSH into the guest and change the box by hand when it gets sick later
- Host fill, nginx, certs, and SSH brute-force never appear unless a separate tool scraped those signals and a rule fired
- A filling /var is a Tink disk warning on every scan — the Web-UI will stay quiet until the next pool or Rock-on process dies
- A single VPS with a dead agent still needs a mechanic, not another snapshot line
For a 5-server team, Tink Mechanic at $45/month is cheaper than a Rockstor NAS plus the engineer who keeps failed-Rock-on notifications alive, and every scan includes a diagnosis a quiet Web-UI poll will not type.
No BTRFS homework. No silent host. One command install.
