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 etc]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 3.8G 3.8G 0 100% /
