I am hoping that someone may be able to help shed some light on a peculiar situation we have with our Moodle installation and submitted files to the Assignment activities. Our Moodle is version 3.0, running on Windows Server 2008R2 (Virtual server), IIS 7.5/SQLServer (not entirely sure which version of SQL Server we’re running… but it lives on a different server to IIS), using PHP 5.4 (I believe, though may have been changed to 5.6… I can find out if needed).
The problem started a couple of weeks ago when one student reported an issue with not being able to access their files that they have submitted so far towards a draft submission. The learner is not able to Edit Submission and can only access the first two documents (there are seven in total). I am also not able to access the files. There are about 50 students enrolled onto this course and all but two are able to use the draft submission as expected.
The second reported problem is with another Moodle page (in the same Moodle site), the tutor or students are unable to access their files once submitted, though this is only happening to two or three learners from the group, however it is consistently happening to these learners for several of the assignment submissions on the course… all other learners are able to use the assignment activity as expected.
The third problem is with submitted files not showing in the grading window, even though the student is showing as having submitted (the submission is time/date stamped, but there are no files). The tutor for this course is also not able to Download All Submissions (though I personally think this may be because each of the submitted files are about 250MB and the operation is timing out).
Now I’m not sure if these occurrences are related, but they need investigating and sorting quickly...
I have access to the moodledata folder and the moodle database, so I can perform simple queries on the data in the database if this will help. My main question is how do I determine WHERE the files are in the moodledata folder? I’ve had a look, but there are a lot of files in there and I don’t know where or how to start looking for these files… if they can be found here at all!
Also, in the temp folder in the moodledata folder there are 33 temp files, some as large as 1.6GB… could these have anything to do with the Download All Submissions failing, or are these just files that will disappear over time?
Sorry for the long post, if any further information is needed I’ll be happy to provide it – any help, suggestions or ideas at all would be appreciated J
Thanks in advance!
