Re: [Crash-utility] SLES 9 Dump
I tried again using kerntypes and it failed with a different error.
# /RedHat/crash-6.1.0-X86/crash vmlinux-2.6.5-7.321-bigsmp dump-pts02504
Kerntypes-2.6.5-7.321-bigsmp

Dave,
I rebuilt 6.1.0 crash as you had suggested.
# file /RedHat/crash-6.1.0-X86/crash
/RedHat/crash-6.1.0-X86/crash: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not
stripped
I then ran it against the dump. I got the following error messages.
# /RedHat/crash-6.1.0-X86/crash vmlinux-2.6.5-7.321-bigsmp dump-pts02504
...
crash: vmlinux-2.6.5-7.321-bigsmp: no debugging data available
I tried again with additional System.map but got the same error.
# /RedHat/crash-6.1.0-X86/crash vmlinux-2.6.5-7.321-bigsmp dump-pts02504
System.map-2.6.5-7.321-bigsmp
...
crash: vmlinux-2.6.5-7.321-bigsmp: no debugging data available

Dave,
On both RHEL 5.2 X64 and RHEL 5.5 X64, it showed: (Additional
argument such as System.map does not make any difference.)
# crash vmlinux-2.6.5-7.321-bigsmp dump-pts02504
...
WARNING: machine type mismatch:
crash utility: X86_64
vmlinux-2.6.5-7.321-bigsmp: X86
crash: vmlinux-2.6.5-7.321-bigsmp: not a supported file format
Right, as the message states, you're trying to analyze a 32-bit
x86 vmlinux/vmcore with the x86_64 version of the crash utility.
So just get the 32-bit x86 crash utility. If you can't find
one, then you can try building one on your x86_64 host:
$ wget http://people.redhat.com/anderson/crash-6.1.4.tar.gz
...
$ cd crash-6.1.4
$ make target=X86
...
$ ./crash vmlinux-2.6.5-7.321-bigsmp dump-pts02504
If the build fails, you can wget the crash-6.1.4-0.src.rpm
file from the same location, and the rpmbuild -ba will alert
you to the additional packages you need.

On an RHEL 4.7 X86, it showed:
# crash vmlinux-2.6.5-7.321-bigsmp dump-pts02504
...

Thanks.

What is the mismatch error message?
