Your running kernel is using more than 70% of the amount of space you reserved for kd
Dear redhat forums members
I have a Redhat EL6 basic server installation. 24Gb Ram,73 Gb disk for OS. swap = 26 Gb.Rest is for / On startup kdump gives the following warning: 'Your running kernel is using more than 70% of the amount of space you reserved for kdump, you should consider increasing your crashkernel reservation' I inserted 'crashkernel=128M rhgb quiet" in the grub.conf file in /etc as per the redhat manual for ES 6. How serious is this warning? Can I disable the kdump and how? = chkconfig kdump off? So then I dont have any dump for a crash yes? What is standard practice? Thanks to all! |
I havent received any replies, so in the end I just chkconfig kdump off. So the warning is gone, but I also dont have a kernel dump now.
Any ideas? |
The kdump setup is required only if you want to bug report a kernel crash.
Or if you want to analyze, what happened, I guess. Anyway : There better be no kernel crashes on EL6 ever. Not very convenient for a server. .. |
After some long searching - the answer is: from Redhat 6.1 for servers with mem greater or equal than 24Gb make the crashkernel=768M in your grub.conf.
Hope this helps someone else as well. Cheers |
