Hello, >Hi I am a university student, and have made some changes to >makedumpfile to produce a gzipped output of core dump.

Can >someone please point out to me the changes I should make to solve this >bug (or can point to the code where this renaming is done). makedumpfile doesn't have such renaming mechanism, it just name the dump as user specify. I guess "vmcore-incomplete" you said is came from kexec-tools. For example, kexec-tools of RHEL7 generate the code below for dump-capture kernel: 110 echo "kdump: saving vmcore" 111 $CORE_COLLECTOR /proc/vmcore $_mp/$KDUMP_PATH/$HOST_IP-$DATEDIR/vmcore-incomplete || return 1 112 mv $_mp/$KDUMP_PATH/$HOST_IP-$DATEDIR/vmcore-incomplete $_mp/$KDUMP_PATH/$HOST_IP-$DATEDIR/vmcore 113 sync $CORE_COLLECTOR is makedumpfile, so the code generate "vmcore-incomplete" by makedumpfile and rename it to vmcore by mv. If you want "vmcore.gzip", you should just specify vmcore.gzip for makedumpfile. Thanks, Atsushi Kumagai
