Centos 6.5版本，df，centos6.5版本df


问题如题，df -h 出来的容量与du -sh 查看的容量信息不一样，是那里出了问题了吗？

下面分别是du -sh *与df -h出来的结果

[root@mail /]# du -sh *

以上是相关查询命令的输出，下面是硬盘fdisk -l的输出信息

[root@mail /]# fdisk -l

[root@mail /]#

之前也使用 badblocks 进行扫描了下，坏的块为0。

实在是找不出来相关的原因了，遂发出来希望路过的大神指点一下。

在此步骤之前也曾怀疑是否是因为有删除文件而没有释放出来而导致的，然后删除了一些文件，容量间也会直接减少，也有进行重启过服务器，小弟菜鸟。在发贴期间仍也会不停的自已进行寻找答案。

 

谢谢！
