Using crash utility usage - cannot find booted kernel error (vmlinux)
I'd like to make an analysis in RH 5.5 for created vmcore file .
According to some docs two kernel packages are required - kernel-debuginfo-version.arch.rpm and
I have these ones :
# yum list | grep debug
kernel-debug.x86_64 2.6.18-194.el5 installed
kernel-debug-devel.x86_64 2.6.18-194.el5 installed
Neither kernel-debug-common-* is not available .
I assume that due to this fact I do not have /usr/lib/debug/lib/modules/ directory with vmlinix in order to proceed with vmcore analysis .
crash: cannot find booted kernel -- please enter namelist argument
Please advise .
please have a look at either our ftp server ftp.redhat.com or the yum utilities as they provide a feature to download debuginfo packages too.
Here are a few links about crash and its usage:
Hope that helps.
