Tells me there's no boot device. UEFI requires the GPT partitioning scheme and a special boot partition on the harddrive, a EFI System Partition (ESP). If you don't have GPT on your drive, your best option is to backup anything precious, redo the partitioning, and reinstall your system. If you already use the GPT partitioning scheme and can make some extra room on your harddrive, then you'll be able to create a small ESP of 800K, and populate that partition with /boot/boot1.efifat. E.g.: gpart create -t efi -s 800K -l esp0 ada0 gpart bootcode -p /boot/boot1.efifat -i <index-of-efi> ada0 -- +-------------------------------+------------------------------------+ | 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 Thu Feb 4 08:31:03 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 C1C3DA9BC00 for <freebsd-questions@mailman.ysv.freebsd.org>; Thu, 4 Feb 2016 08:31:03 +0000 (UTC) (envelope-from matthew@FreeBSD.org) Received: from smtp.infracaninophile.co.uk (smtp.infracaninophile.co.uk [IPv6:2001:8b0:151:1:3cd3:cd67:fafa:3d78]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (Client CN "smtp.infracaninophile.co.uk", Issuer "infracaninophile.co.uk" (not verified)) by mx1.freebsd.org (Postfix) with ESMTPS id 69726AB1 for <freebsd-questions@freebsd.org>; Thu, 4 Feb 2016 08:31:03 +0000 (UTC) (envelope-from matthew@FreeBSD.org) Received: from liminal.local (liminal.infracaninophile.co.uk [IPv6:2001:8b0:151:1:3636:3bff:fed4:b0d6]) (authenticated bits=0) by smtp.infracaninophile.co.uk (8.15.2/8.15.2) with ESMTPSA id u148UwTj048620 (version=TLSv1.2 cipher=ECDHE-RSA-AES128-GCM-SHA256 bits=128 verify=NO) for <freebsd-questions@freebsd.org>; Thu, 4 Feb 2016 08:30:58 GMT (envelope-from matthew@FreeBSD.org) Authentication-Results: smtp.infracaninophile.co.uk; dmarc=none header.from=FreeBSD.org DKIM-Filter: OpenDKIM Filter v2.10.3 smtp.infracaninophile.co.uk u148UwTj048620 Authentication-Results: smtp.infracaninophile.co.uk/u148UwTj048620; dkim=none; dkim-atps=neutral X-Authentication-Warning: lucid-nonsense.infracaninophile.co.uk: Host liminal.infracaninophile.co.uk [IPv6:2001:8b0:151:1:3636:3bff:fed4:b0d6] claimed to be liminal.local Subject: Re: Migrating ZFS on Linux pools to FreeBSD To: freebsd-questions@freebsd.org References: <n8u4d0$2gj$1@ger.gmane.org> From: Matthew Seaman <matthew@FreeBSD.org> X-Enigmail-Draft-Status: N1110 Message-ID: <56B30C42.1030006@FreeBSD.org> Date: Thu, 4 Feb 2016 08:30:58 +0000 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:38.0) Gecko/20100101 Thunderbird/38.5.1 MIME-Version: 1.0 In-Reply-To: <n8u4d0$2gj$1@ger.gmane.org> Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="gSJi9SEoeNCBruLhUobwjtVuUla1At6p9" X-Virus-Scanned: clamav-milter 0.99 at lucid-nonsense.infracaninophile.co.uk X-Virus-Status: Clean X-Spam-Status: No, score=-2.6 required=5.0 tests=ALL_TRUSTED,AWL,BAYES_00 autolearn=ham autolearn_force=no version=3.4.1 X-Spam-Checker-Version: SpamAssassin 3.4.1 (2015-04-28) on lucid-nonsense.infracaninophile.co.uk X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.20 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: Thu, 04 Feb 2016 08:31:03 -0000 This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --gSJi9SEoeNCBruLhUobwjtVuUla1At6p9 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable On 04/02/2016 00:01, Ruben Schade wrote: > I'm migrating a home HP Gen8 Microserver from Debian Jessie to FreeBSD > 10.2.

It'd be cool i= f > it=E2=80=99s just a # zpool upgrade away hah :) So long as the ZFS pool only has feature flags enabled that are supported on both systems, then you should be able to mount your linux-created pool on FreeBSD. A good way to test that is to boot a live FreeBSD image from the install media. See if you can import the pool and then access the contents.
