I started to read that bug a couple of days ago Maybe using 'ConditionVirtualization=container' should be enought to prevent fstrim from running inside container, I'll give it a try later this week. If its work as expected, I'll submit it upstream.
'container' type would cover the following: openvz OpenVZ/Virtuozzo lxc Linux container implementation by LXC lxc-libvirt Linux container implementation by libvirt systemd-nspawn systemd's minimal container implementation, see systemd-nspawn(1) docker Docker container manager podman Podman container manager rkt rkt app container runtime wsl Windows Subsystem for Linux Reference: https://www.freedesktop.org/software/systemd/man/systemd-detect-virt.html# -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to util-linux in Ubuntu. https://bugs.launchpad.net/bugs/1589289 Title: fstrim: cannot open /dev/.lxd-mounts: Permission denied Status in util-linux package in Ubuntu: Confirmed Bug description: fstrim weekly cronjob output in an unprivileged LXD container: /etc/cron.weekly/fstrim: fstrim: cannot open /dev/.lxd-mounts: Permission denied fstrim: /dev/fuse: not a directory fstrim: /dev/lxd: FITRIM ioctl failed: Operation not permitted There is a github issue: https://github.com/lxc/lxd/issues/2030 The outcome is that it's purely an fstrim misbehaviour, it could be smarter. Stephane Graber comment: As all of this is handled by the kernel, there isn't anything we can do about it in LXD. I think fstrim should be made slightly more clever: * Don't run on bind-mounts (you can detect bind-mounts by parsing /proc/self/mountinfo instead of /proc/mounts) * Maybe not be as noisy on expected errors like EACCES, EPERM and ENOENT, only log actual failures which would likely be EINVAL or memory related errors.
