How Do I Remove A Kernel
I have 4 kernels in /boot, leaving on 20MB which is not enough for the next one.
I had installonly_limit= set at 5, as there were some kernel problems.
After I got the error that there was not enough room for another kernel, I set installonly_limit= to 3 and did the update with –exclude=kernel*
That worked to update everything else, but not remove the oldest kernel.
How can I remove the oldest kernel to make room for the new one?
thanks

yum remove kernel-3.10.0-862.2.3.el7.x86_64 # or whatever the name is.
For the YOLO approach
yum remove $( rpm -q kernel | sort -n | head -n 2 )
That should work currently (though a safer method might be done).. I am not sure if it will correctly deal with kernel-3.10.0-1234.5.6.el7.x86_64
someday

Is this ok [y/N]:
Only freed up 12MB. All the other kernel components are still there:
How do I get rid of the whole lot?
thanks
what other components? Can you give some details on what you are seeing staying around? That will help (especially since people didn’t know from the first email you are on a arm system which may have different items than an x86_64)
yum install yum-utils package-cleanup –oldkernels –count=3
replace the count with however many you want to leave on the system.
P.
Oops. My bad for leaving that off, but what about all the kernel* (like
4 rpms?) that normally gets installed?
dtb-4.14.28-201.el7.CentOS.armv7hl initramfs-4.14.28-201.el7.CentOS.armv7hl.img System.map-4.14.28-201.el7.CentOS.armv7hl uImage-4.14.28-201.el7.CentOS.armv7hl uInitrd-4.14.28-201.el7.CentOS.armv7hl vmlinuz-4.14.28-201.el7.CentOS.armv7hl
The dtb* is a directory.
Already installed.

That picked up 110MB and now I have enough room for installing the new kernel.
Thanks.
