This is becoming quite a nuisance for us. In our instance the userDataFiles.chunks collection has grown to 20GB+ making backups unnecessarily slow and painful.

For me this is a huge problem, too. In our instance the userDataFiles.chunks collection has 142GB vs. rocketchat_uploads.chunks collection with just 4.4GB. This make backups unnecessarily slow, painful and storage intensive.

Is it possible to do the cleanup via mongoDB shell? I don't have the courage to simply delete all entries of the collection...

Possible to use mongoDB shell:

use parties
db.rocketchat_userDataFiles.chunks.remove( { } )
db.runCommand({ compact: 'rocketchat_userDataFiles.chunks', force: true });
