Description of problem: Upon kernel crash, kexec runs and kdump is unable to cp the vmcore image because /proc/vmcore is missing: cp: /proc/vmcore: No such file or directory Version-Release number of selected component (if applicable): kexec-tools-1.101-69 + kexec-x86.patch from bug #238768. How reproducible: Happens all the time. Steps to Reproduce: 1. setup kexec-tools normally 2. use "default shell" in /etc/kdump.conf 3. you'll see "cp: /proc/vmcore: No such file or directory" a few lines above the shell prompt Additional info: Tested on two machines: 1. intel xeon dual processor blade (8843-E9U) in an IBM Bladecenter H (8852-4XU). ~6 GB of memory. (64bit machine, fc6-x86 install) 2. IBM ThinkCentre 8183-32U Pentium 4. ~600MB memory (32bit, fc6-x86 install)
Created attachment 155915 [details] patch to turn on vmcore proc file in all kernels for FC6 Now that we have relocatable kernels available in FC-6, we need to enable /proc/vmcore in all of them. This patch should handle that
Dave, would you mind please checking this config change into FC-6? We need this config option enabled now that we have relocatable kernels available in that release. Thanks
I rebuilt kernel with CONFIG_PROC_VMCORE=y and I get a successful dump copy of vmcore and clean reboot of the machine. (the blade x86 install).
