SMART Disk Health: /smart-status
/smart-status [--all] reads the SMART values per disk (verified against smartctl 6.5 on DSM 7.3.1) and assigns a verdict per disk. Passwordless sudo for /usr/bin/smartctl is required (see "Passwordless sudo").
What is evaluated
Per disk: health self-test, temperature, power-on hours, reallocated sectors (attribute 5) and pending sectors (197). From these the verdict follows:
| Verdict | Trigger |
|---|---|
critical | SMART health FAILED, reallocated sectors > 100, pending > 0, or temperature > 55 °C |
warn | health status unknown, 1–100 reallocated sectors, or temperature > 45 °C |
pass | everything in the clear |
Device type
If smartctl returns unexpected output, a different device type often helps. Add smartctl_device_type: sat (or ata, nvme, scsi) to the profile — the default is ata.
Fleet sweep
With --all all NAS are checked in turn, each probed for reachability via BatchMode first. The fleet verdict is the worst of all NAS (ranking ok < warn/unreachable < critical), including a count of unreachable NAS.
