From cc4037d12012244b51a1efecdeb121184efe6f67 Mon Sep 17 00:00:00 2001 From: Vivek Goyal Date: Wed, 5 Sep 2012 17:24:34 -0400 Subject: [PATCH] dracut: Override rd.md settings if rd.md.uuid is provided Currently anaconda provides rd.md=0 on kernel's command line as a boot time optimization if root is not on md device. But this leads to kdump failure. We copy the command line from first kernel and if dump target is on md device, it fails as we never try to assemble md devices as rd.md=0. We have already set rd.md.uuid though in /etc/cmdlind.d/ dir providing dracut the info about what md devices to assemble. So this patch overrides rd.md settings if rd.md.uuid is provided. This is a stop gap measure to get kdump working on software raid devices. Harald seems to have bigger cleanup plans for rd.md. Once that happens, this patch will not be needed and things should automatically be fixed.
