Disabling the crash kernel (and kdump) in CentOS/RHEL 6
Had a system where the user wanted to disable the crash kernel after a previous admin had enabled it. I found a ton of write-ups showing how to enable and configure kdump, but few describing the opposite.
There are multiple approaches that work here, but for a quick win here’s what we did.
- On the kernel line, find the text
crashkernel=and set it to
chkconfig kdump off
If you don’t want to reboot, then you could do
service kdump stop
