VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"

HOME_URL="https://amazonlinux.com/"

Details about issue

I mounted a S3 bucket to a local directory with the following command:

sudo s3fs bucket ~/s3/ -o passwd_file=$HOME/.aws_pass,nonempty,rw,allow_other,mp_umask=002,uid=$UID,gid=$UID -o url=http://s3.us-east-2.amazonaws.com,endpoint=us-east-2,use_path_request_style

then I'm able to ls files in the directory ~/s3/ and I can read some of the files but not others. For the files that I cannot read, I cannot either copy the file to directories on the machine with the command:

cp ~/s3/some_dir/filename ~

The error I got is:

cp: error reading ‘filename’: Input/output error
cp: failed to extend ‘/home/ec2-user/filename’: Input/output error

I'm also able to create new files on that directory, just not able to read or copy files. Any idea of why this is happening? thanks!
