$ pwd

4.0K    srv
0       sys
1.3G    usr
36M     var

$ du -hs var
118M    var

Why is the same directory reporting two different sizes?


You might notice that dev reports a large size, which when added to var produces the same as var by itself (82+36=118). Normally /dev would be almost empty of space, consisting solely of directories and special files.

Perhaps there's some filesystem (or large hard-linked file) mounted in both which du -sh * factors out.
