Hi all,
I am trying to use crash on RHEL 7.0.After executing "crash" command,
it outputs:
crash: cannot find booted kernel -- please enter namelist argument
After referring to crash white paper
(https://people.redhat.com/anderson/crash_whitepaper/),
I know it needs vmlinux file. So I install "kernel-debuginfo" package:
[root@localhost boot]# rpm -ql kernel-debuginfo | grep vmlinux
/usr/lib/debug/lib/modules/3.10.0-123.el7.x86_64/vmlinux
Then execute crash, it still prompts the same error:
crash: cannot find booted kernel -- please enter namelist argument
I try to copy vmlinux file into /boot directory, but this error still exists.
How can I fix this issue? Thanks very much in advance!
Best Regards
Nan Xiao
