Here's a quick laundry list: Ensure all disks are available and visible to the firmware. Someone else on one of the lists made a change to the disk controller, thus limiting the number of visible disks. Once that was rectified everything was back to normal. A description of your zpools layout would be nice. Any changes done to your zpools during operation prior to reboot, like adding disks only visible to the kernel, and not the firmware nor the boot loaders. Try booting one of the 10.3 snapshots to see if the pools are healthy. I hope others might chime in with far better suggestions than mine. -- +-------------------------------+------------------------------------+ | Vennlig hilsen, | Best regards, | | Trond Endrestøl, | Trond Endrestøl, | | IT-ansvarlig, | System administrator, | | Fagskolen Innlandet, | Gjøvik Technical College, Norway, | | tlf. mob. 952 62 567, | Cellular...: +47 952 62 567, | | sentralbord 61 14 54 00. | Switchboard: +47 61 14 54 00. | +-------------------------------+------------------------------------+ From owner-freebsd-questions@freebsd.org Fri Mar 18 16:25:18 2016 Return-Path: <owner-freebsd-questions@freebsd.org> Delivered-To: freebsd-questions@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 8A46FAD4907 for <freebsd-questions@mailman.ysv.freebsd.org>; Fri, 18 Mar 2016 16:25:18 +0000 (UTC) (envelope-from pathiaki2@yahoo.com) Received: from nm42-vm4.bullet.mail.bf1.yahoo.com (nm42-vm4.bullet.mail.bf1.yahoo.com [216.109.114.191]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id 43A00D00 for <freebsd-questions@freebsd.org>; Fri, 18 Mar 2016 16:25:17 +0000 (UTC) (envelope-from pathiaki2@yahoo.com) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=yahoo.com; s=s2048; t=1458318119; bh=mxpG4kl5wAn3iVrJHElGbr7VNdTSIPTtrUtmqk0Zc8A=; h=Subject:To:References:From:Date:In-Reply-To:From:Subject; b=kSYIB9Us6S4z7hi1BDabOxnhLCjPf+tNTNnGnQ4ChdO10rWKwekBVtUMRQORApYpDDmEAdN6U7ewKwbDnU6dlocgXXkO+Vywv+hNl0gx1twJF2x3OxtQb1o8vP/ui8BAOpAgmYhKWKC7er+A9nO80MX/nJ+PnlJ9Mk4p/4cx2o4vvSEZtpCpbWVc4i568TqLhLCFZ1A/srrON679pjshUSSGr7cjWSGSe2w2YM9A37TtyckhZOPPBzbxOGZptGIhx1RmGs21Ud5WqgOUEtL3ILiVzQNw1jLnpJyCRQozL3iZq6scaQ8SI+6kj4ls+v0fL3WKycT39IXjipiqQ8s/NA== Received: from [98.139.170.179] by nm42.bullet.mail.bf1.yahoo.com with NNFMP; 18 Mar 2016 16:21:59 -0000 Received: from [98.139.211.192] by tm22.bullet.mail.bf1.yahoo.com with NNFMP; 18 Mar 2016 16:21:59 -0000 Received: from [127.0.0.1] by smtp201.mail.bf1.yahoo.com with NNFMP; 18 Mar 2016 16:21:59 -0000 X-Yahoo-Newman-Id: 702368.93731.bm@smtp201.mail.bf1.yahoo.com X-Yahoo-Newman-Property: ymail-3 X-YMail-OSG: UwFfpy0VM1nUXZVjrIcoUn9zDLBaZuVhSCmVAUfXeFBN0k1 z0heXoCoz2ewCJi6_x7aCKMemOmP5wBjHWHuL7pw17r22EfcZZBUwcXD8Bk1 I95LkOcwam5o6EfmhVy3VkpqVPc4m.UN1ZRoE1MHjRPBIODbD3O1QV_OnTkX pW5MIYMtOpwHaAugfMyBH5Lxb3uftUaIxUAeKZFry0pFf.NFJUbLfPReJEM. jcQUQ2pdEVr6lmr9AziVcp0JO0Ij9NAinWkIjUFyAonRz.go0OK0_GeeukYq s2pJ7z4rTy314weD9GZhw8xvANdMT0pkTdIRNsjf7HaxOC8gUWpjjsrkyLFV HxdmMUOxe4TTgCSp6ms_L_q6C9_FUZy5B90q1rpsrcvMTE9phVx9E2cD84av I5UcnLf5AhfmEQpmgbSsg0wdjw8Q8Ze7gGnPitdIac8qPSa00sDXVokW8yPk onK26rXsoBHTtvC8k3nVic5hXoawcKZe7zIZ2eBctVK6BU4T5qWY2W7whNBP uAcNREKDirxF1zuk6bmdbBlAyqXcnDdE- X-Yahoo-SMTP: h3Xqg6.swBC0yI913RMMwp94grO_cg-- Subject: Re: unable to boot to FreeBSD 10.1-RELEASE-p31 To: freebsd-questions@freebsd.org References: <B8DFB8650EABA347A6A9036FE8936CA81CD9C2C9@NDMSMBX403.ndc.nasa.gov> <alpine.BSF.2.20.1603181642490.18361@mail.fig.ol.no> From: pathiaki2 <pathiaki2@yahoo.com> Message-ID: <56EC2B25.3020601@yahoo.com> Date: Fri, 18 Mar 2016 12:21:57 -0400 User-Agent: Mozilla/5.0 (X11; FreeBSD amd64; rv:38.0) Gecko/20100101 Thunderbird/38.5.0 MIME-Version: 1.0 In-Reply-To: <alpine.BSF.2.20.1603181642490.18361@mail.fig.ol.no> Content-Type: text/plain; charset=windows-1252; format=flowed Content-Transfer-Encoding: 8bit X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: User questions <freebsd-questions.freebsd.org> List-Unsubscribe: <https://lists.freebsd.org/mailman/options/freebsd-questions>, <mailto:freebsd-questions-request@freebsd.org?subject=unsubscribe> List-Archive: <http://lists.freebsd.org/pipermail/freebsd-questions/>; List-Post: <mailto:freebsd-questions@freebsd.org> List-Help: <mailto:freebsd-questions-request@freebsd.org?subject=help> List-Subscribe: <https://lists.freebsd.org/mailman/listinfo/freebsd-questions>, <mailto:freebsd-questions-request@freebsd.org?subject=subscribe> X-List-Received-Date: Fri, 18 Mar 2016 16:25:18 -0000 On 03/18/2016 11:48, Trond Endrestøl wrote: > On Fri, 18 Mar 2016 15:38-0000, Rao, Uthra R.

Do a man gptzfsboot and follow the examples. You will probably want to stamp a new bootstrap on the boot drive partition. (This is only if you used GPT and the BOOT disk is ZFS - seems to be) Since you probably have the media on a USB or DVD, boot from it and get into a shell and re-stamp the bootstrap on the correct disk. gpart show <RET> will show you the partition table. Chances are, partition 1 is the one you want to stamp and should say freebsd-boot: gpart show => 34 5860533101 ada0 GPT (2.7T) 34 6 - free - (3.0K) 40 1024 1 freebsd-boot (512K) <------SEE THIS? 1064 4194304 2 freebsd-swap (2.0G) 4195368 3032 - free - (1.5M) 4198400 5856333824 3 freebsd-zfs (2.7T) 5860532224 911 - free - (456K)
