根因分析

nginx 存储客户端请求体临时文件的分区（通常是 /var/lib/nginx/tmp 或 /tmp）已满。

English

The filesystem partition where nginx stores temporary client body files (usually /var/lib/nginx/tmp or /tmp) is full.

官方文档

解决方案

  1. Free up space on the partition or move the temp directory to a partition with more space. Example:
sudo du -sh /var/lib/nginx/tmp
sudo rm -rf /var/lib/nginx/tmp/*
# Or change path in nginx.conf:
client_body_temp_path /data/nginx/tmp 1 2;
  2. Increase the partition size if using LVM or cloud storage. For example, on AWS EBS, extend the volume and resize the filesystem.

无效尝试

常见但无效的做法:

  1. 60% 失败

    The buffer only delays temp file creation; large requests will still hit disk.

  2. 50% 失败

    It forces all body data into memory, which can cause OOM for large uploads.

  3. 80% 失败

    Nginx will fail to create the temp directory and return a permission denied error.
