du 和df看到的文件大小不一致。做过重挂。做过fsck，做过重启都没有效果。有兄弟碰到过类型的情况没？查看其它 12 个回答jiaxu2000的回答
du -g
du traverses the file tree, adding up the number of blocks allocated to each
directory, symlink, and file as reported by the stat() system call. This is how
du arrives at its total value.
df -g
df looks at the file system disk block allocation maps to arrive at its total
and free values.
Disk blocks get assigned when a process is started and it will hold the disk block. It might use additional disk blocks for meta data. This additional disk blocks will get tracked by df-g but not du -g. Thus, df command will usually report high storage usage as compared to du. However, if the disk blocks got locked by a process and you use another application to delete the disk blocks, du will reflect the change but df will not.
