We bought a R320 with the H310 Mini PERC last year. The server runs stable/10 amd64. I managed to convince the PERC to run in JBOD mode. The four drives are exposed as /dev/mfisyspd0, /dev/mfisyspd1, /dev/mfisyspd2, and /dev/mfisyspd3. ZFS hasn't complained so far, but the mfi driver complains every now and then about not being allowed to run patrol read: mfi0: 1063 (531025200s/0x0020/WARN) - Patrol Read can't be started, as PDs are either not ONLINE, or are in a VD with an active process, or are in an excluded VD -- +-------------------------------+------------------------------------+ | 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 Mon Nov 21 13:58:25 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 3B74BC4C881; Mon, 21 Nov 2016 13:58:25 +0000 (UTC) (envelope-from dweimer@dweimer.net) Received: from webmail.dweimer.net (24-240-198-187.static.stls.mo.charter.com [24.240.198.187]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id E6073FBA; Mon, 21 Nov 2016 13:58:24 +0000 (UTC) (envelope-from dweimer@dweimer.net) Received: from webmail.dweimer.local (localhost [10.9.5.2]) by webmail.dweimer.net (8.15.2/8.15.2) with ESMTPS id uALDejxS014998 (version=TLSv1.2 cipher=DHE-RSA-AES256-GCM-SHA384 bits=256 verify=NO); Mon, 21 Nov 2016 07:40:45 -0600 (CST) (envelope-from dweimer@dweimer.net) Received: (from www@localhost) by webmail.dweimer.local (8.15.2/8.15.2/Submit) id uALDeiYu014977; Mon, 21 Nov 2016 07:40:44 -0600 (CST) (envelope-from dweimer@dweimer.net) X-Authentication-Warning: webmail.dweimer.local: www set sender to dweimer@dweimer.net using -f To: Trond Endrestøl <Trond.Endrestol@fagskolen.gjovik.no> Subject: Re: Dell R230's + ZFS via PERC MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit Date: Mon, 21 Nov 2016 07:40:44 -0600 From: "Dean E.

I have a couple of machines running on Dell PERC H700, with zfs running on JBOD setup, looks like they are successfully running it. mfi0: 14748 (532234800s/0x0020/info) - Patrol Read started mfi0: 14789 (532250323s/0x0020/info) - Patrol Read complete mfi0: 14790 (532839600s/0x0020/info) - Patrol Read started mfi0: 14835 (532854948s/0x0020/info) - Patrol Read complete These machines are under fairly low load outside of 6am to 6pm time frame. -- Thanks, Dean E.
