OpenClaw workspace disk garbage collection on MacLogin cloud Mac: April 2026 prune runbook that keeps gateways online without deleting your queues

When OpenClaw gateways on leased Apple Silicon minis start timing out, teams blame “the model API” long after the real culprit is a full APFS volume. April 2026 practice: treat disk like a queue dependency—snapshot utilization, classify directories into safe versus destructive buckets, prune with manifests, and only bounce launchd jobs after openclaw doctor shows green headroom. This runbook inventories hot paths, publishes a binary decision matrix, sequences eight operator steps, ties log rotation to unified logging caps, mandates state backup before destructive deletes, and closes with FAQ for Hong Kong, Tokyo, Seoul, Singapore, and United States fleets.

Pair with state directory backup handoff, doctor diagnostics, and npm peer dependency rebuild after aggressive cache clears. Public anchors: help and pricing.

Symptoms that scream disk before they scream OpenClaw

Disk pressure disguises itself as flaky automation. Watch for:

• Gateway health checks succeed locally yet webhook acknowledgements arrive in bursts—often log fsync stalls.
• Node package installs that previously took two minutes suddenly exceed ten, especially after OpenClaw plugin upgrades that unpack tarballs into workspace scratch.
• macOS popups about “storage almost full” appearing during Screen Sharing sessions while engineers still insist “we only run text agents.”

Hot path inventory: what grows fastest on multi-tenant cloud Macs

Not every megabyte belongs to OpenClaw, but the gateway process collocates with developer cruft. Use this inventory table during weekly hygiene; extend rows for your org’s custom plugin paths.

Path pattern	Typical growth driver	Safe trim	Destructive if wrong	Notes
~/.openclaw/tmp	Webhook replay buffers	Yes after ticket	No	Rotate when older than 72 hours
~/.npm caches	Plugin installs	Yes	Medium	Expect longer next install
~/Library/Logs unified logging mirrors	Verbose gateway weeks	Yes with caps	Low	Coordinate with SOC2 retention
~/.openclaw/state queues	Stuck jobs	No without backup	High	Drain queues first

Binary prune matrix (answer quickly under incident pressure)

Question	If YES	If NO
Did doctor JSON export attach to the ticket?	Proceed with safe tmp deletes	Stop—run doctor first
Was tarball backup taken in the last 30 minutes?	Allow destructive soul-memory archive rotation	Take backup via handoff guide
Is another engineer Screen Sharing?	Defer large deletes	Continue with IO-light passes

Eight-step runbook (April 2026 revision)

1. Freeze outbound experiments that spawn new sandboxes until pruning completes.
2. Capture df -h and inode stats into the incident ticket.
3. Export openclaw doctor --json (or your org’s equivalent) before mutating disk.
4. Archive ~/.openclaw with hashed tarball names per the backup article.
5. Prune tmp, rotated logs, and old plugin build artifacts following the inventory table.
6. Vacuum npm caches if peer drift rebuild is planned anyway.
7. Bounce gateway via launchctl kickstart -k only after confirming at least 15 GB free.
8. Re-export doctor JSON and diff against step three; attach diff to close the ticket.

Gateway logs, unified logging, and why “just delete Console” is lazy

macOS unified logging can absorb gigabytes when debug modes linger after incidents. Cap retention at the gateway layer by routing structured JSON lines to a bounded file with daily rotation and seven cold copies unless compliance requires more. When shipping logs off-host, compress before upload—Screen Sharing-friendly bandwidth matters for humans still debugging alongside bots.

State backup before destructive passes (non-negotiable)

OpenClaw’s value is continuity: queued webhooks, half-completed tool approvals, and soul-memory pointers. Deleting “just the cache” without reading symlinks has bricked more labs than any CVE discussion. Follow state directory backup handoff literally—hash archives, store them outside the lease when possible, and document who holds the encryption key.

Regional footprint: HK, JP, KR, SG, and US operator realities

Disk pressure is not evenly distributed. Singapore and Hong Kong leases often host cross-border CI bursts that fill npm caches faster than single-region US teams expect. Japanese enterprises frequently enforce longer log retention—plan rotation policies per country, not per generic “cloud” rule. Korean gaming-adjacent clients may store large asset bundles beside OpenClaw; isolate those directories with separate quotas. United States customers mixing Ollama weights with OpenClaw should mount weights on secondary volumes when available.

When footprint grows beyond three concurrent gateway experiments, split leases using pricing instead of infinite pruning—hardware is cheaper than pager fatigue.

FAQ

Does MacLogin auto-prune my workspace? Customers own file lifecycle; we expose capacity—see help for recommended monitoring hooks.

Should I disable plugins to save disk? Only after measuring; plugins may be smaller than their caches.

What about Docker? If you colocate containers, prune images separately; this article focuses on OpenClaw-native paths.

Why Mac mini M4 unified memory helps OpenClaw under disk churn

When APFS performs copy-on-write during large workspace copies, unified memory bandwidth on M4 keeps the gateway responsive while tarballs stream. That matters for Seoul and Tokyo teams running simultaneous doctor exports. Renting additional minis from MacLogin to separate “experiment” and “production” gateways reduces destructive prune frequency and keeps incident windows shorter.

Pair hardware scale-up with operational discipline: start every quarter with a dry-run of this runbook on a non-production lease cloned from pricing templates, then promote only the automation that survived the drill.
