Explanation of makedumpfile:
To shorten the size of the dumpfile and the time of creating the
dumpfile, makedumpfile copies only the necessary pages for analysis
to the dumpfile from /proc/vmcore. You can specify the kind of
unnecessary pages with dump_level. If you want to shorten the size
further, enable the compression of the page data.
Download:
You can download the latest makedumpfile from the following URL.
Details of the change are written on the git page of the following site.
https://sourceforge.net/projects/makedumpfile/
Method of installation:
You can compile the makedumpfile command as follows;
1. "tar -zxvf makedumpfile-x.y.z.tar.gz"
2. "cd makedumpfile-x.y.z"
3. "make; make install"
Usage:
makedumpfile [-c|-l|-p|-E] [-d dump_level] [-x vmlinux] dump_mem dump_file
Example:
If you want to exclude pages filled by zero, cache pages, user pages
and free pages and to enable compression, please execute the following
command.
# makedumpfile -l -d 31 /proc/vmcore dumpfile
Thanks,
Kazu
