linux - LVM ボリュームで「df」と「du」が異なる使用済みスペース値を表示するのはなぜですか?

Question

[root@local ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      524G  465G   32G  94% /
/dev/sda1              99M   13M   82M  14% /boot
tmpfs                  18G     0   18G   0% /dev/shm
[root@local ~]# du -hs /
57G /

なぜショーは同じではありませんが、私はそれほど多くのスペースを使用しませんでした.

Chances are that you deleted a file that was still being written to. While it won't be picked up by du (it only looks at files that still 'exist"), df will notice the missing free space. Try a lsof | grep deleted
