I mounted my S3 bucket on Ubuntu 14.0, by following instructions in S3FS-Fuse. I can see the content of the bucket in the folder. But when I try to paste something in the folder, I'm getting permission denied error:

This error is when trying to upload from Node Multer. Even trying locally Copy/Paste fails with same error. Tried chmod 777 mys3mt/ and get Input/output error :

On the bucket in AWS console, I've given Read and Write Permission for Everybody for both, Object Access and Permissions Access. Anything uploaded to the S3 bucket is listed in Ubuntu. But I am not able to add anything from Ubuntu.

What am I missing? Please help.

Many thanks.
