fstrim.service successfully runs as scheduled by fstrim.timer, but skips the /home partition.
Mail moved shortly after reboot by postfix/local does not show up in the folder of the user, but suddenly appears hours later, when new mail gets moved.
Hi
If you manually run the fstrim -v /home does it provide more information? There are a number of fstrim threads, one thing in common seems to be samsung devices… The firmware is all up to date on the NVMe?

Running fstrim manually works fine. Firmware is up to date. Noticed the problem when mail would show up only delayed some weeks ago.

erlangen:~ #
Switched to a new system partition using btrfs and kept home partition. Same symptoms as before: fstrim skipped /home and after several days email would not show up anymore at ~/.local/share/local-mail/. Fixed fstrim.service and everything is back to normal now.
