Synology capacity notifications (retired)

Whrrr previously ran scripts/hotfix-syno-capacity.sh from DSM Task Scheduler every 30 minutes. The script posts directly to ntfy when any /volume* mount is at least 90% used; Alertmanager silences and OneUptime acknowledgement do not affect it.

Static capacity warnings are retired as of 2026-08-29. Current hardware cannot be expanded economically, and deleting retained data is not an accepted remediation. Capacity remains visible through DSM and storage dashboards without recurring phone notifications.

Disable the live DSM task

This is an owner action because the Synology DSM task runs as root:

  1. Open Control Panel → Task Scheduler on Whrrr.
  2. Find the user-defined task whose script invokes /volume1/scripts/homelab/hotfix-syno-capacity.sh.
  3. Disable the task. Do not delete the script, its environment file, the ntfy topic, or any volume data.
  4. Leave it disabled for more than 30 minutes and confirm no capacity push arrives.

The repository script also defaults CAPACITY_ALERT_MODE to disabled. If the deployed script is updated before the DSM task is disabled, an existing environment file without that variable safely becomes a no-op:

DISABLED: standalone Synology capacity notifications are retired

Re-enabling

Do not re-enable threshold pushes without a new actionable capacity policy. Reactivation requires both an owner decision and CAPACITY_ALERT_MODE=enabled. Prefer a stateful or centrally monitored design with an explicit remediation over restoring 30-minute repeated notifications.
