Hey guys, 3 years ago I followed https://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/Mirror for a FreeBSD 8.1 system (which has since been upgraded to 9.1). A couple days ago I had massive hardware failure, and wound up having to put the two drives into an entirely new PC system. Unfortunately I'm not able to get it to boot off the hard drives. It doesn't even show the FreeBSD bootloader menu it normally would. The BIOS sees both drives and it can boot off the 9.1 install/Live CD without any problems. In the LiveCD, I can see both drives partition tables ("gpart show ..") and I can import the zpool ("zpool import zroot"), and see all my data. I just can't seem to boot from it. I tried rerunning the "gpart bootcode" commands on both drives (no errors), but no effect. It's also not beyond the realm of possibility I have some BIOS setting wrong, but the drives do show up in the POST and BIOS setting. Does anyone know how I can make my drives bootable again? Thanks. --Andy From owner-freebsd-stable@FreeBSD.ORG Thu Sep 19 06:50:35 2013 Return-Path: <owner-freebsd-stable@FreeBSD.ORG> Delivered-To: stable@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [8.8.178.115]) (using TLSv1 with cipher ADH-AES256-SHA (256/256 bits)) (No client certificate requested) by hub.freebsd.org (Postfix) with ESMTP id 034D795B for <stable@freebsd.org>; Thu, 19 Sep 2013 06:50:35 +0000 (UTC) (envelope-from lars@netapp.com) Received: from mx11.netapp.com (mx11.netapp.com [216.240.18.76]) (using TLSv1 with cipher RC4-SHA (128/128 bits)) (No client certificate requested) by mx1.freebsd.org (Postfix) with ESMTPS id DA4D42747 for <stable@freebsd.org>; Thu, 19 Sep 2013 06:50:34 +0000 (UTC) X-IronPort-AV: E=Sophos;i="4.90,935,1371106800"; d="asc'?scan'208";a="51121205" Received: from vmwexceht05-prd.hq.netapp.com ([10.106.77.35]) by mx11-out.netapp.com with ESMTP; 18 Sep 2013 23:50:34 -0700 Received: from SACEXCMBX01-PRD.hq.netapp.com ([169.254.2.46]) by vmwexceht05-prd.hq.netapp.com ([10.106.77.35]) with mapi id 14.03.0123.003; Wed, 18 Sep 2013 23:50:33 -0700 From: "Eggert, Lars" <lars@netapp.com> To: Rick Macklem <rmacklem@uoguelph.ca> Subject: Re: nfsd CPU usage?

I've been running for a day or so after the MFC, and CPU loads are WAY down. Plus, the cache issues I had haven't reappeared either. I need to bang on it some more, but for now it seems great.
