Hi,
makedumpfile version 1.4.2 is released.
Your comments/patches are welcome.
This version is released earlier than usual because 1.4.1 has
compilation error in some architectures.
Changelog:
o New feature
- [PATCH] s390x: Auto-detect the correct MAX_PHYSMEM_BITS used in vmcore being analyzed.
(for s390x 64TB memory by Mahesh Salgaonkar) 440ed48
o Bugfix
- [PATCH] Fix compilation error in sadump_info.h. (by Michael Holzheu) 25ae552
o Code Cleanup
- [PATCH] Add Makefile parameter to use dynamic libraries. (by Atsushi Kumagai) 67b2be2
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] [-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 -c -d 31 -x vmlinux /proc/vmcore dumpfile
Thanks
Atsushi Kumagai
