linux 删除文件硬盘大小未变化
最近游戏服务器硬盘爆满。
奇怪的是用 du /opt/
看只有25g
但是df看
却是
檔案系統 容量 已用 可用 已用% 掛載點
/dev/sda5 195G 23G 163G 13% /
/dev/sda2 68G 65G 0 100% /opt
/dev/sda1 99M 12M 82M 13% /boot
tmpfs 16G 0 16G 0% /dev/shm
搞不明白为什么会是65g
在/opt/目录下执行du --max-depth=1 -h
也只是20多G
后来无意间发现
lsof |grep delete命令可以查看已经删除的但是系统仍然在用的文件这些文件不会释放磁盘空间
才看到 有很多这样的资源 导致硬盘爆满

然后结束这些服务后重启 服务
用df 查看
