for an explanation of why transfer to your library server is failing for files that have been uploaded to your fsua3 access server.

It seems unlikely that the portfolio quota would be responsible for a failure to transfer an uploaded file from an access server to a library server.  The student will see a message (from the access server itself): "Unable to upload ... Disk quota will be exceeded" if a student attempts to upload a file to the portfolio that will result in the quota being exceeded.

If the file is large, and/or the server was busy, you might look in /home/httpd/perl/logs/lonnet.log for messages such as: "Failed to transfer <filename> to host <host>: error: Timeout"
LWP::UserAgent has a default timeout of 180 s, and the fetch_user_file_handler() routine in lond also sets alarm(120).

Once a user's portfolio's quota is reached additional files can not be uploaded to the portfolio.  An exception to that is the "Browse" button within an assignment, which can be used by a student to upload a file into the "turned_in" subdirectory within the student's portfolio, even if the portfolio quota has already been reached.

Once a file in a student's portfolio has been submitted to a homework assignment, it is locked until it has been graded.  When it is graded, a copy of the file is created, and the original file is unlocked.  Once unlocked a student can delete the file, but the graded copy will remain, accessible to a Course Coordinator, via the grading interface.

The graded copy is *not* included when a student's portfolio quota usage is calculated, but the original file uploaded by the student is included in the student's quota usage, until deleted by the student.

Not currently.  A domain coordinator can increase the portfolio quota for specific types of user (e.g., faculty, staff or students), or for an individual user.

I have now added an enhancement request to allow a DC to update the portfolio quota for multiple users in a single course via the "Manage Users" screen.  See: bugs.loncapa.org/show_bug.cgi?id=6928

Hi all,

Still trying to figure out why essay submissions failed to transfer to the lib server. One possibility may be that the size of the portfolio for the students is too small. Is there a way to increase the size (MB) for a whole class? Thanks.
