From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050921 Red Hat/1.0.7-1.4.1 Firefox/1.0.7 Description of problem: savecore needs to support a new CLI flag that integrates gzip compression on-the-fly so vmcore does not take so much space in /var/crash. I had a 64GB host netdump the other day and it took 18 hours over an OC-12 WAN to dump. When I gzip'd the core, it was ~9GB. Solaris compresses their vmcore files by default. I would like to see an option added to /etc/sysconfig/diskdump that /etc/init.d/diskdump would read and pass to $SAVECORE. This option would enable gzip on-the-fly. It might increase the time savecore takes to run, but it would mean I wouldn't need to have a 64GB /var/crash and a 64GB dump partition (both a waste) if I want to transition from netdump to diskdump. Version-Release number of selected component (if applicable): diskdumputils-1.1.8-1 How reproducible: Always Steps to Reproduce: 1. Initiate kernel dump with diskdump enabled 2. /var/crash/vmcore is uncompressed Actual Results: /var/crash/vmcore is the size of RAM Expected Results: /var/crash/vmcore.gz would be a fraction of the size of RAM and would allow for easy transfer to Red Hat support for kernel engineer analysis.
