SSD trim

[jarmala]

Kas vaan, huomasin juuri, että joskus sitä SSD:täkin trimmataan:

Koodia: [Valitse]

$ systemd-analyze blame
    6min 12.314s fstrim.service
         19.789s apt-daily.service
          4.331s plymouth-quit-wait.service
          3.898s apt-daily-upgrade.service
          1.282s snapd.service
          1.057s dev-sda1.device

Koskaan ennen huomannut moista. Lienee normaalia? Eh?

Trim (discard) is enabled to run weekly by default in 18.04.
It is a systemd service managed via systemctl, not CRON.
fstrim is set to run for all mounted filesystems on devices that support the discard operation.

Active: inactive (dead) tulee minulla, siksipä olen ajastanut fstrim:in cronilla kerran viikossa

Jees. Noinhan se taitaa olla:

Koodia: [Valitse]

$ systemctl status fstrim.timer

Eli varmaan ajettiin ensimmäisen kerran, joten se vei aikaa peräti kuusi minuuttia...
