How do I generate a kernel memory core dump (vmcore) on my system? Our system entered a hung state or became unresponsive, how can we troubleshoot? How much time is required to capture a vmcore? How much disk space is required to generate a vmcore?
A minidump is a smaller version of a complete, or kernel memory dump. Usually Microsoft will want a kernel memory dump. But the debugger will analyze a mini-dump and quite possibly give information needed to resolve. If it's all you have, then debug it, rather than waiting for...
Install the correspondingkernel-debuginfopackage of the kernel version from which the kernel crash dump was collected. Eg: Raw # yum install kernel-debuginfo-4.18.0-32.el8.x86_64 Open the kernel crash dump using thecrashutility. Eg: Raw # crash vmcore /usr/lib/debug/lib/modules/4.18.0-32...
