used明显比size小，但是Avail怎么是0，Use是100%呢：
df /
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 6190692 5944048 0 100% /

10% is reserved for root only.

Another possible reason: there is a(or many) apps opened a lot of files,
this may consume all available inode of the file system. You may check it by
comparing df and du output.
