SMART monitoring

SMART monitoring bewaakt de gezondheid van uw schijven.

In deze pagina kunt u het monitoren en de schijf-selftest in- of uitschakelen per schijf.

Opmerking Wanneer u het monitoren van een schijf uitschakeld, wordt de schijf-selftest ook automatisch uitgeschakeld.

Het uitschakellen van de selftest is nodig bij sommige schijven, omdat de performance van het systeem dan te langzaam word. Ook gebeurd het bij bepaalde schijven dat de selftest blijft hangen, waardoor performance problemen ontstaan.

De monitoring check gebeurd ieder uur. De selftest gebeurd elke nacht.

Status uitlezen via de shell

Dit kan op de volgende manier:

Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

Zo kunt u ook zien of er nog een selftest gaande is en wat er precies aan de hand is.

Met smartctl -X /dev/sda kunt u een selftest onderbreken.
