linux – rsync：写入失败 – 设备上没有剩余空间(28)

我想rsync文件夹从一个服务器到另一个服务器.

但rsync同步失败：

$rsync -zr --compress-level=9 --delete /var/www/mywebsite/current/web/js login@192.168.1.4:/srv/data2_http
rsync: write Failed on "/srv/data2_http/js/8814c77.js": No space left on device (28)
rsync error: error in file IO (code 11) at receiver.c(322) [receiver=3.0.9]
rsync: connection unexpectedly closed (21747 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(605) [sender=3.0.9]

但我有足够的空间！

解决方法

rsync首先将内容传输到目标文件夹中的临时文件;如果成功,则将该临时文件重命名为目标文件.如果传输失败,则删除临时文件.一个2GB的文件会填满你的目标空间,然后在rsync删除它后,空间再次可用.所以,rsync可以欺骗你对空间问题的调查.
