centos安装求助！

在我点击确定安装后出现:安装时出现以下错误。这是个致命错误，安装将终止YumPRMTransError:Could not run transaction
installing package cjkunj-uming-fonts-0.2.2008021
6.1-53.el7.noarch needs 11MB on the / filesystem
installing packagelohit-tamil-fonts-2.5.3-2.el7.
noarch needs 11MB on the / filesystem
.......省略较多代码
省略的代码差不多都和上面一样，installing package开头，noarch needs on the / filesystem结尾求大神帮小弟分析下是什么错误，感激不尽
