J'ai installé et mis en place smartd pour exécuter de courts tests SMART tous les jours et de longs tests SMART une fois par semaine, et m'avertir lorsque des erreurs sont consignées:

Subject: SMART error (SelfTest) detected on host: inspiron
X-Mailer: mail (GNU Mailutils 3.1.1)
This message was generated by the smartd daemon running on:
host name: inspiron
DNS domain: [Empty]
The following warning/error was logged by the smartd daemon:
Device: /dev/sda [SAT], Self-Test Log error count increased from 0 to 2
Device info:
Crucial_CT275MX300SSD4, S/N:163613DAF037, WWN:5-00a075-113daf037, FW:M0CR021, 275 GB
For details see host's SYSLOG.
You can also use the smartctl utility for further investigation.
Another message will be sent in 24 hours if the problem persists.
Les courriels me conseillent de "voir le SYSLOG de l'hôte", mais le syslog ne contient smartctl signaler tout ce qui sort de l'ordinaire:
# grep smart </var/log/syslog
