[Crash-utility] Is there a way to validate the coherency of a kdump-compressed dumpfile ?

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
