我无法将大于 20 M 的文件上传到我的 S3 存储桶
I can't upload files bigger then 20 M to my S3 bucket
我最近在 Scaleway 创建了一个 S3 存储桶。
我使用 s3fs 安装它没有明显问题。
我在上传一些 "mid size" 文件时遇到问题。
如果大小小于 20 M，则没问题，但对于较大的文件（50 M 或更多），复制失败并显示消息 "unable to write file, permission denied"。
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桶，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copy/paste日志的最后100行，因为我看不出错误在哪里。
非常感谢帮助

你从哪里安装你的桶？是您家中的 PC 还是云 VM？收到此错误需要多长时间？
我问是因为 "SSL_write() returned SYSCALL, errno = 32" 看起来有什么东西正在关闭你的连接。 "HTTP error before end of send, keep sending" 也为这类问题点赞。可能发生超时？您和您的存储桶之间是否有 NAT 网关？这也可能导致问题，如果它不关心 keepalive，因为上传可能需要相对较长的时间。
正如 s3fs wiki 所说，20MB 是分段上传而不是单个请求的阈值。也许 Scaleway 对于分段上传的 API 与 Amazon 略有不同？来自 s3fs wiki："Some providers do not support the full S3 API, e.g., lacking multi-part upload." 请注意，s3fs 主要用于与 Amazon S3 一起使用，正如我所见，Scaleway 不在 s3fs wiki 中的受支持提供商列表中：https://github.com/s3fs-fuse/s3fs-fuse/wiki/Non-Amazon-S3。
最后，你的 libcurl 版本是多少？ s3fs 文档说它应该是 7.16 或 7.17。您使用的是最新版本的 s3fs 吗？
我使用您的命令行参数成功安装并写入了一个 500 MB 的文件到 scaleway。鉴于 CURLE_SEND_ERROR 我想知道您是否遇到某种网络问题？也许为 -o parallel_count 尝试一个较低的值，例如 1？请参阅 https://github.com/s3fs-fuse/s3fs-fuse/issues/1283#issuecomment-623026911 了解解决方案。
我最近在 Scaleway 创建了一个 S3 存储桶。 我使用 s3fs 安装它没有明显问题。 我在上传一些 "mid size" 文件时遇到问题。 如果大小小于 20 M，则没问题，但对于较大的文件（50 M 或更多），复制失败并显示消息 "unable to write file, permission denied"。 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桶，使用：

你从哪里安装你的桶？是您家中的 PC 还是云 VM？收到此错误需要多长时间？
我问是因为 "SSL_write() returned SYSCALL, errno = 32" 看起来有什么东西正在关闭你的连接。 "HTTP error before end of send, keep sending" 也为这类问题点赞。可能发生超时？您和您的存储桶之间是否有 NAT 网关？这也可能导致问题，如果它不关心 keepalive，因为上传可能需要相对较长的时间。
正如 s3fs wiki 所说，20MB 是分段上传而不是单个请求的阈值。也许 Scaleway 对于分段上传的 API 与 Amazon 略有不同？来自 s3fs wiki："Some providers do not support the full S3 API, e.g., lacking multi-part upload." 请注意，s3fs 主要用于与 Amazon S3 一起使用，正如我所见，Scaleway 不在 s3fs wiki 中的受支持提供商列表中：https://github.com/s3fs-fuse/s3fs-fuse/wiki/Non-Amazon-S3。
最后，你的 libcurl 版本是多少？ s3fs 文档说它应该是 7.16 或 7.17。您使用的是最新版本的 s3fs 吗？
我使用您的命令行参数成功安装并写入了一个 500 MB 的文件到 scaleway。鉴于 CURLE_SEND_ERROR 我想知道您是否遇到某种网络问题？也许为 -o parallel_count 尝试一个较低的值，例如 1？请参阅 https://github.com/s3fs-fuse/s3fs-fuse/issues/1283#issuecomment-623026911 了解解决方案。
