[SMART](https://fr.wikipedia.org/wiki/Self-Monitoring,_Analysis_and_Reporting_Technology) (Self-Monitoring, Analysis and Reporting Technology) est intégrée à la plupart des disques durs pour avoir des indicateurs de diagnostic. Sous Linux/Unix, [Smartmontools](https://www.smartmontools.org/) est l'outil pour exploiter la technologie SMART, notamment avec la commande `smartctl` et le démon `smartd`.

## Utilisation
### Lister les disques
Sur une machine avec un seul disque :
~~~
# smartctl --scan
/dev/sda -d scsi # /dev/sda, SCSI device
~~~
Sur une machine avec du RAID hardware :
~~~
# smartctl --scan
/dev/hdd -d ata # /dev/hdd, ATA device
/dev/sda -d scsi # /dev/sda, SCSI device
/dev/sdb -d scsi # /dev/sdb, SCSI device
/dev/sdc -d scsi # /dev/sdc, SCSI device
/dev/bus/0 -d megaraid,0 # /dev/bus/0 [megaraid_disk_00], SCSI device
/dev/bus/0 -d megaraid,1 # /dev/bus/0 [megaraid_disk_01], SCSI device
/dev/bus/0 -d megaraid,2 # /dev/bus/0 [megaraid_disk_02], SCSI device
/dev/bus/0 -d megaraid,3 # /dev/bus/0 [megaraid_disk_03], SCSI device
/dev/bus/0 -d megaraid,4 # /dev/bus/0 [megaraid_disk_04], SCSI device
/dev/bus/0 -d megaraid,5 # /dev/bus/0 [megaraid_disk_05], SCSI device
