[LON-CAPA-admin] checking course quotas

Thank you for reporting this.

Given that this is a Domain Coordinator utility it seems that it is most likely to be run in a user session on the library server, hence no one has reported this discrepancy before.

The quota usage data for the "Display quotas and usage for Course/Community Content" will be for disk usage on the course's home server (i.e., your library server), where all data are permanently stored.

When the quotacheck.pl script is run on a library server, the disk usage values (in MB) are retrieved directly from the filesystem on that server.  However, when the script is run on a server that is not the course's home server (e.g., on an access server), a request for the data needs to be sent to the library server.  In that instance the routine called (remotely) to compute disk usage was returning a total in KB, instead of MB.

Anyway, the usage numbers (and percentages) in the screenshot from the library server are the correct ones.  The usage numbers on the access server need to be divided by 1024.

I have just filed a bug (6961) and committed an updated quotacheck.pl script (rev. 1.9) to fix the bug.  The new version includes a division by 1024 (to convert from KB to MB). 

See bugs.loncapa.org/show_bug.cgi?id=6961

If you would like to update the version of quotacheck.pl on an access server (running LON-CAPA 2.11.2 or 2.11.3) to 1.9, see the bug report for instructions.

When I do the following on our access server and our library server:

Status of domain servers --- Display quotas and usage for Course/Community Content --- Select user “datta” --- Search

I get vastly different results from each server.  See the attached images (these show courses from just this semester, there are so many more)

It does the same with other users also.  Why is this the case?

SIDE NOTE:  Without going into too much detail, this user started uploading uncompressed video (it got worse when we went online last year).  I’m sure more questions will come concerning this issue…
