cron+fstrim+ssd logolása

Csak hogy lássam, hogy egyáltalán csinál e valamit!


root@ubuntu:/etc/cron.weekly# cat ./fstrim 
#!/bin/sh
# script datas for logging
ME=$(basename $0)
MP=$$

# trim all mounted file systems which support it
/sbin/fstrim --all -v | while read MSG; do
    /usr/bin/logger -t "${ME}(${MP})" "${MSG}"
done

#test
#grep "fstrim\([0-9]*\)" /var/log/syslog
exit 0

Az SSD nem tamogatja a nativ trimet ?

de. csak úgy lassabb, és még az ezzel foglalkozó oldalak többsége is azt mondja, hogy érdemesebb hetente/naponta fstimet használni inkább.
kevesebb lesz az írási művelet. - állítólag -

hogy ténylegesen mennyivel kevesebb fene tudja. mindenesetre az fstrim benne van a cronban eleve, csak nincs loggolva. hogy miért nem lehetett azt a 3 sort hozzáírni, azt sem tudom.

Ha a meghajtó támogatja a qTRIM-et nyugodtan használhatod a discard opciót! Aztán a vezérlő majd eldönti mikor, mit, hogyan...
