you mention " Instead of using Amazon S3 (and this extension), you can create an Amazon EFS drive and mount it to $wgUploadDirectory. It's recommended for small wikis".
I have created an EFS drive and mounted it to my instance where the wikis is being run.
But how can I make this EFS drive the uploadDirectory in the LocalSettings? I have a DNS for this EFS but that's it?
Thanks Tristan
