liunx df -h

     liunx下 解压db2 数据库，发现报错：

tar: server/db2ls: Cannot write: No space left on device

tar: Skipping to next header

server/installFixPack

tar: server/installFixPack: Cannot write: No space left on device

tar: Skipping to next header

tar: Error exit delayed from previous errors

     最后发现是由于空间不够造成

df -h 可以查看文件系统的大小

[root @localhost etc]# df -h
