## Summary Adds a staging VM disk-usage monitor + daily cleanup cron, fixing the gap surfaced by #1684 (staging hit 100% disk during a hot-patch, no alert, no cleanup). ## What landed - **`scripts/staging/disk-monitor.sh`** — parses `df -P <mount>`, classifies usage `<80 ok / >=80 warn / >=90 error / >=95 alert`, emits to stderr + journald via `logger -p`, exits non-zero on `error|alert` so the systemd unit surfaces as failed. - **`scripts/staging/disk-cleanup.sh`** — daily prune of `/tmp` snapshot patterns (`*.db`, `staging-snap.*`, `cs-*`, `node-compile-cache`) older than 7d + `docker builder/image prune --filter until=72h --filter label!=keep`. Honors `CORESCOPE_CLEANUP_DRY_RUN=1`. - **`scripts/staging/test-disk-monitor.sh`** — pure-bash unit tests for the testable helpers (22 cases covering threshold boundaries, df parsing, invalid input, severity→priority mapping). - **`DEPLOY.md`** — install one-liner with full inline systemd unit + timer content (15-min monitor, daily 03:30 cleanup). Uses `<STAGING_HOST>` placeholder. - **`.github/workflows/deploy.yml`** — wires `test-disk-monitor.sh` into the Go build & test job. ## TDD - Commit `26185967` (RED): tests against stub helpers — `PASS=5 FAIL=17` on assertions. - Commit `d31a1082` (GREEN): real helpers — `PASS=22 FAIL=0`. ## Phase 3 — `staging-snap.db` root cause `grep -rn staging-snap.db cmd/ public/ scripts/` → **zero hits**. The 4.4 GB orphan was a manual debug artifact, not committed code. The cleanup retention rule prevents recurrence. Partial fix for #1684 — leaves issue open for operator to verify install on staging and confirm alert fires at 85%. --------- Co-authored-by: corescope-bot <bot@corescope.local> Co-authored-by: clawbot <bot@openclaw.dev>

## Staging VM — disk-usage monitor & cleanup (#1684)
|
||||
|
||||
The staging VM ran out of disk during a hot-patch (#1684). To prevent
|
||||
repeats, two scripts live in `scripts/staging/`:
|
||||
|
||||
- `disk-monitor.sh <mount>` — reads `df -P`, classifies usage against
|
||||
`<80 ok / >=80 warn / >=90 error / >=95 alert`, emits to stderr +
|
||||
journald (via `logger`). Returns non-zero on `error|alert` so
|
||||
systemd surfaces the unit as failed.
|
||||
- `disk-cleanup.sh` — removes `/tmp` snapshot files (`*.db`,
|
||||
`staging-snap.*`, `cs-*`, `node-compile-cache`) older than 7 days
|
||||
and runs `docker builder prune` + `docker image prune` with
|
||||
`--filter "until=72h" --filter "label!=keep"`. Set
|
||||
`CORESCOPE_CLEANUP_DRY_RUN=1` to log without deleting.
|
||||
|
||||
### Install on the staging host
|
||||
|
||||
SSH to `<STAGING_HOST>` as the staging operator user and:
|
||||
|
||||
```bash
|
||||
sudo install -m 0755 scripts/staging/disk-monitor.sh /usr/local/bin/corescope-disk-monitor
|
||||
sudo install -m 0755 scripts/staging/disk-cleanup.sh /usr/local/bin/corescope-disk-cleanup

|

`<STAGING_HOST>` is the staging VM hostname/IP — operator supplies it,
|
||||
not committed to the repo.
|
||||
|
||||
### Inspecting alerts
|
||||
|
||||
```bash
|
||||
journalctl -t corescope-disk-monitor --since '-1d'
|
||||
journalctl -t corescope-disk-cleanup --since '-7d'
|
||||
systemctl list-timers | grep corescope-disk
|
||||
```
|
||||
|
||||
`logger` priorities map: `ok→info`, `warn→warning`, `error→err`,
|
||||
`alert→alert` (syslog severity 1, the highest level). Wire
|
||||
`journalctl -p alert ...` to whatever ops channel the operator
|
||||
prefers; use `-p err` to also catch the `error` tier.
|
||||
|
||||
### Notes on `staging-snap.db` root cause (#1684 phase 3)
|
||||
|
||||
`grep -rn staging-snap.db cmd/ public/ scripts/` returns **zero**
|
||||
hits in the repo. The 4.4 GB orphan was a manual debugging artifact,
|
||||
not produced by any committed code. The `disk-cleanup.sh` retention
|
||||
rule (anything matching `staging-snap.*` in `/tmp` older than 7 days)
|
||||
prevents recurrence without needing source-side TTL changes.
|
||||
|
||||
If a future feature legitimately needs persistent snapshot DBs, put
|
||||
them under `/var/lib/corescope/snapshots/` with explicit rotation —
|
||||
not in `/tmp`, which is ephemeral by definition.
