Hello, makedumpfile version 1.5.2 is released. Your comments/patches are welcome. Main new feature: o Support for eppic language This feature enables us to specify rules to scrub data in a dumpfile with eppic macro instead of the current configuration file (makedumpfile.conf). Currently, this feature works only for symbols in vmlinux while the current feature can work also for module symbols. To use this feature, you should build the extension module as below and move it to your library directory: # make eppic_makedumpfile.so To build this module, you should prepare eppic library from the following URL: http://code.google.com/p/eppic/ o Exclude hwpoison page This is the default action in new makedumpfile. This feature excludes hwpoison pages in any dump_level, we can avoid touching poisoned pages and running into MCE during dump process.

(by Atsushi Kumagai) 3104500 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
