As mentioned in the systemd-posting I migrated back to an SSD today (on my main rig, the thinkpad uses an SSD happily for a long time now).
A feature in a local magazine updated my knowledge of how to make use of the TRIM-command. It told me not to use the mount-option "discard" anymore, but run fstrim on the mountpoint frequently. OK, I learn ;-) But, AFAI understand, after trimming sectors/bytes on the filesystem/partition, they should be trimmed. I expect X bytes to be trimmed at first and if I repeat the command, I expect 0 (or something pretty low) bytes to be trimmed then, ok? This is what I wonder about: ~ # fstrim -v / /: 6195433472 bytes were trimmed ~ # fstrim -v / /: 6195433472 bytes were trimmed ~ # fstrim -v / /: 6195433472 bytes were trimmed I tested it with "discard" on and off. / is ext4, yes, and on an SSD, yup. Do I misunderstand things here? Thanks, Stefan
