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
[[email protected] /]# du -sh * 6.2M bin 22M boot 172K dev 29M etc 165G home 130M lib 26M lib64 16K lost+found 4.0K media 4.0K mnt 4.0K opt du: 无法访问"proc/9139/task/9139/fd/4": 没有那个文件或目录 du: 无法访问"proc/9139/task/9139/fdinfo/4": 没有那个文件或目录 du: 无法访问"proc/9139/fd/4": 没有那个文件或目录 du: 无法访问"proc/9139/fdinfo/4": 没有那个文件或目录 0 proc 0 result.txt 201M root 15M sbin 4.0K selinux 4.0K srv 0 sys 40K tmp 6.3G usr 349M var [[email protected] /]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup-lv_root 50G 44G 3.4G 93% / tmpfs 2.4G 0 2.4G 0% /dev/shm /dev/sda1 485M 32M 428M 7% /boot /dev/mapper/VolGroup-lv_home 586G 165G 392G 30% /home [[email protected] /]# cat /etc/redhat-release CentOS release 6.5 (Final) [[email protected] /]#
以上是相关查询命令的输出，下面是硬盘fdisk -l的输出信息

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！
