Re: [Crash-utility] EXT: Re: Is there a way to validate the coherency of a kdump-compressed dumpfile ?
Hello,
Thanks for pointing that.
'help -D' is a good entry point .
Best regards,

Hello,
I’m trying to setup an analyze procedure (with scripts) and would like to ‘check’ the
dumpfile before starting the interactive mode of ‘crash’.
Is there a ‘crash’ option, command that would just :
Return a status to say ‘dumpfile is OK to be processed by crash’.
This should need to finish session initialization, and
Display a header that I could parse.
"help -D" command displays the dumpfile's header.
So I think the exit status and output of this might help, but it takes some time as you
know.
$ echo 'help -D' | crash -s vmlinux vmcore
Thanks,
Kazu
Or ?
Or should I grab directly in the dumpfile (Hmm… kdump-compressed seems not to be easy to
parse) ?
More possibilities with an ELF formatted dumpfile ?
Thanks.
Best regards,
