I hesitated about posting here and resurrecting it, but I figured it'd be for the benefit of others searching about this problem with gentoo. I eventually traced the problem to a script while shutting down, it killed all running processes (including mdmon.) I had an almost working solution, and with a collaboration with someone else on the gentoo forums, there's a full solution now. The forum thread is @ http://forums.gentoo.org/viewtopic-t-888520.html I've reported it as a bug on the bugtracker, I've also got a workaround for it on that bug report: https://bugs.gentoo.org/show_bug.cgi?id=395203 The workaround still hasn't made it into the main repository. Hopefully this will get threaded properly... -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
