Title:
fstrim: cannot open /dev/.lxd-mounts: Permission denied
Status in util-linux package in Ubuntu:
In Progress
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.
