[Crash-utility] disk_dump_header status value

Hello, I have a dump file produced by makedumpfile with following command: /sbin/makedumpfile -d 0 -c --message-level 7 /proc/vmcore /tmpd/crashdump-`date +"%Y%m%d-%H%M"` When I edit the raw binary, it seems that the first bytes could be mapped to a disk_dump_header structure. Is that correct ? When doing this, all seems to match: signature (KDUMP), header version (6), utsname content, timestamp. But not the status: I get 1 (INCOMPLETED), tough I'm able to analyze it with 'crash'. I was expecting 0 or at least 8, because it should be zlib-compressed. What am I missing ? Thanks. Best regards, Patrick Agrain
