=0A=0AHey guys,=0A=0A3 years ago I followed=A0https://wiki.freebsd.org/Root= OnZFS/GPTZFSBoot/Mirror =A0for a FreeBSD 8.1 system (which has since been u= pgraded to 9.1). =A0 =A0A couple days ago I had massive hardware failure, a= nd wound up having to put the two drives into an entirely new PC system.=0A= =0AUnfortunately I'm not able to get it to boot off the hard drives. =A0It = doesn't even show the FreeBSD bootloader menu it normally would. =A0The BIO= S sees both drives and it can boot off the 9.1 install/Live CD without any = problems. =A0 In the LiveCD, I can see both drives partition tables ("gpart= show ..") and I can import =A0the zpool ("zpool import zroot"), and see al= l my data. =A0 I just can't seem to boot from it. =A0 I tried rerunning the= "gpart bootcode" commands on both drives (no errors), but no effect. =A0= =0A=0AIt's also not beyond the realm of possibility I have some BIOS settin= g wrong, but the drives do show up in the POST and BIOS setting.=0A=0ADoes = anyone know how I can make my drives bootable again? =A0=A0=0A=0AThanks.=0A= =0A--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?
