smartctl

Settings à mettre de base

/usr/sbin/smartctl --smart=on --offlineauto=off --saveauto=on /dev/sda

Lancer un "short test" (attendre au moins 2 minutes avant de consulter le résultat)

smartctl -t short /dev/sda

Les options possible sont : offline, short, long, conveyance, force, vendor,N, select,M-N, pending,N, afterselect,[on|off]

smartctl -A /dev/sda

Afficher le log d'erreur

smartctl -l error /dev/sda

Produces output only if the device returns failing SMART status, or if some of the logged self-tests ended with errors.

smartctl -q errorsonly -H -l selftest /dev/sda

Examine all SMART data for device /dev/sda, but produce no printed output. You must use the exit status (the $? shell variable) to learn if any Attributes are out of bound, if the SMART status is failing, if there are errors recorded in the self-test log, or if there are errors recorded in the disk error log.

smartctl -q silent -a /dev/sda ; echo $?

Afficher le log du selftest

smartctl -l selftest /dev/sda

Affiche toutes les informations

smartctl -a /dev/sda

smartctl -a /dev/sda | grep -E 'Media_Wearout_Indicator|Wear_Range_Delta|SSD_Life_Left|Wear_Leveling_Count'

SMART est-il activé?

smartctl -a /dev/sda

Tests réussit?

-a, --all
        Prints all SMART information about the disk, or TapeAlert information about the tape drive or changer.  For ATA devices this is equivalent to
        ´-H -i -c -A -l error -l selftest -l selective´
        and for SCSI, this is equivalent to
        ´-H -i -A -l error -l selftest´.
        Note that for ATA disks this does not enable the non-SMART options and the SMART options which require support for 48-bit ATA commands.


-x, --xall
       Prints all SMART and non-SMART information about the device. For ATA devices this is equivalent to
       ´-H -i -g all -c -A -f brief -l xerror,error -l xselftest,selftest
       -l selective -l directory -l scttemp -l scterc -l devstat -l sataphy´.
       and for SCSI, this is equivalent to
       ´-H -i -A -l error -l selftest -l background -l sasphy´.
