Hello
With which migration module does this happen?
None. I was just explaining where a large data set suddenly arrived from: a 5GB zip from another server, which was then extracted.
Nothing to do with migration modules, much to do with how CWP handles quotas. To reiterate..
How does one force a quota update?Try it for yourself.
1. Give a (test) user a disc quota of 100MB
2. Copy/upload files to the user's home, that is at least 100MB
3. Check what quota says - should say over quota
4. Delete the files from user
5. Check what quota says.
