Oracle 12c数据库在linux mint 18.1上的安装情况

Question

当我在linux mint 18.1 cinnamon上安装oracle 12c时，得到以下错误。

[INS-32021] Installer has detected that the available disk space on the volume for Oracle home (/u01/app/oracle/product/11.2.0/dbhome_1) is insufficient.
[INS-35212] Insufficient disk space on this volume for the selected datafiles location.

df -h的输出如下。

$ df -h

该怎么做呢？
