Overvågning er vigtig hvis man vil sikre sine data, specielt kritisk er det at vide hvordan ens diske har det.
Til dette formål findes SmortMonTools
Installering af SmartMonTools er nem og hurtig.
apt-get install smartmontools
Herefter skal man sikre at ens diske understøtter S.M.A.R.T og dette er enabled.
Denne LinuxServer har 2 Sata diske, derfor køre jeg

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.
det samme gøres naturligvis også for sdb, hvilket forhåbentlig giver det samme output.
smartctl -a /dev/sdb
For at få servicen til at køre skal der tilpasset lidt i /etc/default/smartmontools
vi /etc/default/smartmontools
# uncomment to start smartd on system startup
start_smartd=yes
# uncomment to pass additional options to smartd on startup
smartd_opts="--interval=1800"
Herefter bør man kigge forbi /etc/smartd.conf og sikre at smartmontools sender emails til en konto som overvåget, gør man ikke noget er det Root som vil modtage emails.
vi /etc/smartd.conf
# The word DEVICESCAN will cause any remaining lines in this
# configuration file to be ignored: it tells smartd to scan for all
# ATA and SCSI devices. DEVICESCAN may be followed by any of the
# Directives listed below, which will be applied to all devices that
# are found. Most users should comment out DEVICESCAN and explicitly
# list the devices that they wish to monitor.
DEVICESCAN -m This email address is being protected from spambots. You need JavaScript enabled to view it. -M exec /usr/share/smartmontools/smartd-runner
Tilsidst start smartmontools
/etc/init.d/smartmontools start
Herefter skulle man gerne se noget a'la dette i syslog
