我从过去六个月开始几乎定期使用 WinSCP。
突然我遇到一个问题，那就是我无法使用它在服务器上传文件。
它抛出以下错误信息：
General failure (server should provide error description).
Error code: 4
Error message from server: Failure
Common reasons for the Error code 4 are:
- Renaming a file to a name of already existing file.
- Creating a directory that already exists.
- Moving a remote file to a different filesystem (HDD).
- Uploading a file to a full filesystem (HDD).
- Exceeding a user disk quota.

我用 Google 搜索了该问题，发现这可能是由于文件系统已满 100% 造成的。
我在 centos 中使用以下命令检查了内存：
free -m
命令输出：
total used free shared buff/cache available
Mem: 32014 28612 310 1553 3091 1533
Swap: 0 0 0
好像我有 1533 MP 可用空间。但我仍然无法上传 1 Mb 的小文件。
df 命令输出：
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/vda1 52416860 52416840 20 100% /
devtmpfs 16374100 0 16374100 0% /dev

有人可以提供这方面的信息吗？
答案1
因此，看来您的文件系统确实已满：Use%是100%文件系统/dev/vda1，应该由/home/centos路径使用
