Re: [Crash-utility] crash start in CentOS 8

Hello, I tried to test the crash utility from CentOS 8 with following requirements: First machine (VMware) on which CentOS 8 is installed and on which I performed a fake crash using SysRq. After reboot, The /var/crash was populated with the vmcore. Second machine (Server) on which CentOS 8 is also installed and on which I wish to analyze the crash. Both machine have the same CentOS build installed. I imported System.map-4.18.0-147.el8.x86_64, vmcore and vmlinux.debuginfo from first machine to a directory on the second machine. When I run ‘crash’, I have following messages (see below), but no ‘crash>’ prompt. What have I missed ? What Should I check ? Thanks. Best regards, Patrick Agrain [root@lxkmg-pag-ale test64]# /usr/bin/crash System.map-4.18.0-147.el8.x86_64 vmlinux.debuginfo vmcore crash 7.2.6-2.el8 Copyright (C) 2002-2019 Red Hat, Inc.
