/boot housekeeping + linux

/boot is almost full + linux

It is recommended to have at least 1GB of space for /boot.  

The safest way of cleaning up /boot is :

Do the following to keep just the last 2 kernels on your system, to keep /boot clean.

1 - Edit /etc/yum.conf and set the following parameter

# vi /etc/yum.conf

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 utility so the package-cleanup command will work:

# yum install yum-utils

 

3 - Make an oldkernel cleanup:

# package-cleanup --oldkernels --count=2

4. This will clear lots of space. If not, then we can note down the current kernel version and can move the other kernels files to another directory.

To know current version of kernel:

# uname -r

Or

# rpm -qa kernel

Move other kernel files to another directory

# mv /boot/<file name> /root/oldkernels
