我最近在Scaleway创建了一个S3存储桶。我使用s3fs安装它，没有明显的问题。我上传一些"中等大小"的文件时遇到问题。如果大小小于20 M，可以，但对于较大的文件(50 M及以上(，复制失败，并显示消息"无法写入文件，权限被拒绝"。我联系了scaleway支持，但他们说这与我的s3fs客户端有关。我在调试模式下安装了bucket，使用：
$ sudo s3fs tellurix /mnt/scaleway/ -o passwd_file=${HOME}/.passwd-s3fs,url=https://s3.fr-par.scw.cloud,allow_other -o use_path_request_style,noatime -o dbglevel=info -f -o curldbg
我复制/粘贴日志的最后100行，因为我看不出错误在哪里。非常感谢的帮助

我使用命令行参数成功地安装并编写了一个500 MB的文件到scaleway。考虑到CURLE_SEND_ERROR，我想知道你是否有某种网络问题？也许可以为-o parallel_count尝试一个较低的值，例如1？看见https://github.com/s3fs-fuse/s3fs-fuse/issues/1283#issuecomment-623026911。
您从哪里安装铲斗？它是你家里的电脑还是云虚拟机？您需要多长时间才能收到此错误？
我之所以这么问，是因为"SSL_write((return SYSCALL，errno=32"看起来像是有什么东西正在关闭您的连接。"发送结束前出现HTTP错误，继续发送"也指出了这种问题。可能发生超时？你和你的bucket之间有NAT网关吗？如果它不关心keepalives，这也可能导致问题，因为上传可能需要相对较长的时间。
正如s3fswiki所说，20MB是多部分上传的阈值，而不是单个请求。Scaleway的多部分上传API可能与Amazon略有不同？从s3fs维基："一些提供商不支持完整的S3 API，例如，缺乏多部分上传。"请注意，s3fs主要用于与Amazon S3合作，正如我所看到的，Scaleway不在s3fs维基中支持的提供商名单上：https://github.com/s3fs-fuse/s3fs-fuse/wiki/Non-Amazon-S3.
最后一件事，你的libcurl版本是什么？s3fs文档中说应该是7.16或7.17。你使用的是最新版本的s3fs吗？
