Moin!
Ich habe hier Gentoo Linux mit dem rootfs auf einer ext4-GPT-Partition ohne LVM oder LUKS oder sonst was auf einer Samsung 840 Basic 250GB laufen. So im Gentoo-Wiki empfohlen habe ich / mit nodiscard gemountet und fstrimDemon eingerichtet. Im Logfile sehe ich dann alle paar Tage sowas:
Code
Mi 15. Jan 21:24:05 CET 2014: RUN FSTRIM FOR /
/: 79,8 GiB (85681704960 bytes) trimmed
Das letzte mal vor Gestern sind solche Riesentrims am Sonntag und am Mittwoch davor aufgetreten (sonst nur einige GiB/Tag).
Ich hatte zunächst das tägliche Syncen des Portage-Trees in Verdacht, aber das habe ich seit Freitag nicht mehr gemacht.
