Is there a way to validate the coherency of a kdump-compressed dumpfile ?

[Agrain Patrick <patrick.agrain@xxxxxxxxxxxxxxxxx>]

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’.
• Display a header that I could parse.
• 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,

Patrick Agrain
