Lab 13.2: Creating "bigfile2" that passes quota doesn't print warning on Ubuntu 14.04

Following Lab 13.2 on Ubuntu 14.04, I noticed that when I create a file that passes my "quota" (the soft limit, I guess), I saw no warning about passing my quota. The output from "quota" reflects my passing the quota. Creating the file that passes the hard limit does properly report the error message.

Does Ubuntu allow reporting the quota warning as an option, or does it just not do it?

  • Hi,

    I have Ubuntu 15.10, so it may not be the same if I try on my system. Can you make sure if passing the soft limit is not sending any message? Please also paste here all the commands you are executing (and the outputs you are getting).

    Thanks,
    Luis.

    After creating a a file with "dd", I added it to fstab with the following line:

    /tmp/imgfile /mnt/tempdir ext4 loop,usrquota 1 1

    I then ran the exact "quota..." commands specified in step "2" of the lab solution (except for the user name being different).

    I ran the specified "edquota" line and set soft/hard limits of 500 & 1000.

    I then ran the following as the user:

  • Hi,

    From the man page of mount:

    'The sixth field, (fs_passno), is used by the fsck(8) program to determine the order in which filesystem checks are done at reboot time. The root filesystem should be specified with a fs_passno of 1, and other filesystems should have a fs_passno of 2'.

    In fact it's 2 in the lab file. Can you modify that and try again, please?

    For another hand, what distro and version are you using?

    Thanks,
    Luis.

    No change (I didn't have the impression that "filesystem checks" would include quota processing).

    The new /etc/fstab line is this:

    /tmp/imgfile /mnt/tempdir ext4 loop,usrquota 1 2

    Here's an excerpt from the "uname -a" output: "3.19.0-43-generic #49~14.04.1-Ubuntu".
  • Hi,

    I'll need to get that Ubuntu version and try it. I'll get back to you as soon as possible.

    Thanks,
    Luis.
