[3.7] Maximum file size for restoring course

I have a course backup that is 6 Gigabyte.

Now I have tries to restored this in multiple Moodle instances on different servers. It never succeeded.

Sometimes I get to 99% green bar but 100% failed. On other servers I get a Json error.

Moodle does not create useful log files when a restore fails.

Is there a max file size for course restoration? Because if there is, I need to know about it. I now have many course backups that I can't restore.

It normally depends on the file_upload_size and post_max_size in your php config and then some timeout settings as well. Sometimes I have better luck if I upload the file to something like Google drive and then set that up as a repository. I was having trouble with timeouts (I think) trying to restore a large file and restoring from Drive repository allowed it to restore successfully.

Check web server error logs for 'MySQL has gone away' errors.

As well as:

mysql> show variables like 'max_allowed_packet';

Thanks both for your reply. I upload the course file to the repository on the same Moodle server, so this is not the problem. I can also get through the restore screens until the restoring procedure starts.

'...until the restoring procedure starts'

That's when max packets would come into play.

So, again, web server error logs?   MySQL has gone away?

Query for DB settings for max allowed packets is?

In moodledata/temp/backup/ there should be folders with long names ... inspect one of them.  One of the very last things done ... clean up of that directory - erasing contents then directory but only after restore has completed successfully.  Ownerships/permissions?

Task or cron job task for cleaning up temp areas romping on a restore process?

Are locks being cleared?

Turn on debug!???

Thanks Ken, I will follow these pointers.

To be clear: I get to the restoring screen, 99% restore is green... then 100% restore is failed. I will check with the tech department for further info

Took a while, but we found some more info using Moosh.

Problem seems to be the mod_choicegroup plugin.

Are you restoring on the same site - if not, does the site you are restoring have those plugins installed?  Have you checked for updates on the plugins?

Seems that Turnitin changed the name of their plugin. Therefor, I did not receive any plugin update notifications.

I now updated to their latest version. Let's hope these errors will be solved.

Also, I posted a new issue with mod_chiocegroup with the above sceenshot.

Thanks again Ken for helping and sharing smile
