조치 방법

----------------------------------------------

1 - Edit /etc/yum.conf and set the following parameter  
installonly_limit=2
This will make your package manager keep just the 2 last kernels on your system(including the one that is running)


----------------------------------------------

2 - Install yum-utils:     아래 3번 커맨드가 없을 시
yum install yum-utils


3- Make an oldkernel cleanup:
package-cleanup --oldkernels --count=<남길 커널 버전 갯수>
