For example, when writing a > 5 GB single part object to AWS it rejects it:

head: s3fs: [ERR] curl.cpp:RequestPerform(2282): HTTP response code 400, returning EIO. Body Text: <?xml version='1.0' encoding='UTF-8'?><Error><Code>EntityTooLarge</Code><Message>Your proposed upload exceeds the maximum allowed object size.</Message><RequestId>4442587FB7D0A2F9</RequestId></Error>

This manifests to users as EIO instead of the more specific EFBIG.
