Ok, I asked because according to mount(2) that option appears to be
ignored except for xfs filesystems.

If you look at /proc/self/mountinfo you'll see that usrquota is in fact
in the list of mount options, so lxc is respecting that.

At the moment your problem is that the device backing your rootfs,
/dev/lxc/test, does not exist in the container.  Once you add that (for
instance using a lxc.mount.entry to bind it in or using a
lxc.hook.autodev), I suspect you'll run into other problems.  I can't
get quota to be happy here using a loop-backed rootfs, but a real device
should get you further.

  Disk quotas don't work in LXC containers

Status in lxc package in Ubuntu:
  Confirmed

  I'm trying to enable disk quotas in LXC container by adding option to its config:
  lxc.rootfs.options = usrquota

  After booting the container I'm trying to initialize quotas but
  getting the following error:

  root@xxxxxxxx:~# quotacheck -gum /
  quotacheck: Cannot stat() mounted device /dev/lxc/test: No such file or directory
  quotacheck: Mountpoint (or device) / not found or has no quota enabled.
  quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option.
