Public bug reported: When I was running disco, fstrim.service would trim all of my partitions:
Oct 21 00:00:18 computer systemd[1]: Starting Discard unused blocks on filesystems from /etc/fstab... Oct 21 00:00:37 computer fstrim[9588]: /home: 25 GiB (26797150208 bytes) trimmed on /dev/mapper/ubuntu--vg-home Oct 21 00:00:37 computer fstrim[9588]: /boot: 805.4 MiB (844546048 bytes) trimmed on /dev/sda5 Oct 21 00:00:37 computer fstrim[9588]: /: 5.5 GiB (5929816064 bytes) trimmed on /dev/mapper/ubuntu--vg-root Oct 21 00:00:37 computer systemd[1]: fstrim.service: Succeeded. Oct 21 00:00:37 computer systemd[1]: Started Discard unused blocks on filesystems from /etc/fstab. After upgrading to eoan, my /home partition is no longer trimmed: Oct 28 00:00:21 computer systemd[1]: Starting Discard unused blocks on filesystems from /etc/fstab... Oct 28 00:00:32 computer fstrim[24667]: /boot: 781.1 MiB (819011584 bytes) trimmed on /dev/sda5 Oct 28 00:00:32 computer fstrim[24667]: /: 7.2 GiB (7696994304 bytes) trimmed on /dev/mapper/ubuntu--vg-root Oct 28 00:00:32 computer systemd[1]: fstrim.service: Succeeded. Oct 28 00:00:32 computer systemd[1]: Started Discard unused blocks on filesystems from /etc/fstab. Checking the unit file (/lib/systemd/system/fstrim.service), I noticed there is a "ProtectHome=yes" option. Removing this option caused my /home partition to be trimmed once again. I believe the "ProtectSystem=strict" option may also cause partitions in non-standard partition schemes to be skipped by fstrim.service (although I have not tested this). ** Affects: util-linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1858152 Title: fstrim.service no longer trims /home partition To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1858152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
