solaris5.9操作系统df 和du命令查看磁盘空间占用差距大

swaggerhe

最近系统/opt磁盘目录占用大，于是通过 du 跟df 命令查看了，发现差距好大。

-h 数值显示采用易读方式，例如14K,14K,234M,2.7G,or 3.0T

bash-2.05# du  -h /opt
   .......
  43M   /opt/psm2/pmpcontainer-psm/webapps/pmpcontainer/WEB-INF
  43M   /opt/psm2/pmpcontainer-psm/webapps/pmpcontainer
  81M   /opt/psm2/pmpcontainer-psm/webapps

   1K   /opt/logbak

显示/opt占用 9.3G ,
而df -h /opt占用68G
bash-2.05# df -h /opt
