S.M.A.R.T. info
S.M.A.R.T. drive health monitoring in RouterOS: read drive health, temperature, use and error counters with the /disk smart-info command, and what the reported attributes mean.
S.M.A.R.T. info
S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) is a monitoring system built into modern storage drives. It lets you read diagnostics of the drive: overall health, temperature, use, error counters and, for NVMe drives, the SMART/Health attributes.
信息
S.M.A.R.T. information requires the Storage package. For any attached storage device that supports S.M.A.R.T., read the diagnostics with the
/disk/smart-infocommand:
[admin@MikroTik] > /disk/smart-info nvme1
[admin@R2DUTRDS22162XG4S4XS2XQ20DISKS] > disk/smart-info nvme1

Reading the output
The important values for drive health:
SMART overall-health self-assessment test result- the drive reports whether it considers itself healthy. A drive that reportsFAILEDshould be replaced.Temperature- the current temperature of the drive. The warning and critical thresholds are listed in the information section.Available Spare- how much spare capacity the drive still has before it cannot remap bad blocks. When it drops to theAvailable Spare Threshold, the drive is close to the end of its life.Percentage Used- the estimated lifetime use of the drive, based on the manufacturer's rated endurance. At 100% the drive has reached its rated lifespan.Unsafe ShutdownsandMedia and Data Integrity Errors- how often the drive lost power unexpectedly and how many data errors it detected. Repeated unsafe shutdowns increase the risk of corruption.
The output is the same as smartctl reports on Linux, so the S.M.A.R.T. documentation of the drive vendor applies.
说明
Some USB enclosures cannot pass S.M.A.R.T. information through. If the drive is behind such an enclosure,
/disk/smart-inforeports an error even though the drive itself supports S.M.A.R.T.
