How I can diagnose problem deeply, and maybe g= ive > some useful information for resolving that issue? It is hard to give good general advice in this case. You could maybe see if there are any error messages in your /var/log/messages file. You could also monitor the wchan of the hung process and verify if it's stuck in the "wdrain" state (in "top"). Maybe you could see if there is a problem with interrupts on the machine (either by using "systat -vm" or "vmstat -i"). You could run "iostat -x" and see if the %busy column is 100% while there are many queued requests.= If you install smartmontools, you can run a couple of tests just in case (try smartctl /dev/ada0 and smartctl -t long /dev/ada0). =2E.. but if the problem is an incompatibility with the driver, all this will probably not help you much. --------------enig244217C6789B38AEDFE8237C Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlE91O8ACgkQ/QjVBj3/HSywBQCdGOBKIOMYwjJbwFBTmUC2xeBY aWYAnRZHZZq4eRXdMCJfjqB31A0GwDHc =vO61 -----END PGP SIGNATURE----- --------------enig244217C6789B38AEDFE8237C-- From owner-freebsd-hardware@FreeBSD.ORG Fri Mar 15 10:27:51 2013 Return-Path: Delivered-To: hardware@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by hub.freebsd.org (Postfix) with ESMTP id 9EF8A674 for ; Fri, 15 Mar 2013 10:27:51 +0000 (UTC) (envelope-from amdmi3@amdmi3.ru) Received: from smtp.timeweb.ru (smtp.timeweb.ru [92.53.116.43]) by mx1.freebsd.org (Postfix) with ESMTP id 5FD99126 for ; Fri, 15 Mar 2013 10:27:51 +0000 (UTC) Received: from [213.148.20.85] (helo=hive.panopticon) by smtp.timeweb.ru with esmtpsa (TLS1.0:DHE_RSA_CAMELLIA_256_CBC_SHA1:256) (Exim 4.80) (envelope-from ) id 1UGQQb-0006yt-II for hardware@FreeBSD.org; Fri, 15 Mar 2013 12:55:53 +0400 Received: from hades.panopticon (hades.panopticon [192.168.0.32]) by hive.panopticon (Postfix) with ESMTP id 01C78B84D for ; Fri, 15 Mar 2013 12:55:52 +0400 (MSK) Received: by hades.panopticon (Postfix, from userid 1000) id 695A2AD2; Fri, 15 Mar 2013 12:55:52 +0400 (MSK) Date: Fri, 15 Mar 2013 12:55:52 +0400 From: Dmitry Marakasov To: hardware@FreeBSD.org Subject: Uneven disk throughput distribution Message-ID: <20130315085552.GD99263@hades.panopticon> MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Disposition: inline User-Agent: Mutt/1.5.21 (2010-09-15) X-BeenThere: freebsd-hardware@freebsd.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: General discussion of FreeBSD hardware List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 15 Mar 2013 10:27:51 -0000 Hi! Not sure if it's FreeBSD problem, but I thought it won't hurt to write about it. I'm playing with a set of new 3TB Seagate ST3000VX000-1CU166 hard disks. Each disk does 160-180MB/s write throughtput with `dd if=/dev/zero of=/dev/adaX bs=10m`, but when all disks are written to simultaneously, throughput distribution is uneven: ada1: 174032158720 bytes transferred in 1486.316119 secs (117089599 bytes/sec) ada2: 174199930880 bytes transferred in 1487.372522 secs (117119234 bytes/sec) ada3: 172805324800 bytes transferred in 1488.324386 secs (116107299 bytes/sec) ada4: 169376481280 bytes transferred in 1489.353551 secs (113724831 bytes/sec) ada5: 157642915840 bytes transferred in 1490.324518 secs (105777577 bytes/sec) ada6: 112449290240 bytes transferred in 1491.338958 secs (75401564 bytes/sec) I guess that summary performance drop is to be expected due to bus/controller throughput cap, but uneven distribution is strange, and if it may be fixed, it may improve performance of large raid arrays. The system is FreeBSD 9.0 amd64. PS. I've tried the same thing on Debian live system. Similar pattern of throughput drop towards the last disk, however the difference is even worse: 142, 140, 136, 130, 117, 49 MB/s -- Dmitry Marakasov . 55B5 0596 FF1E 8D84 5F56 9510 D35A 80DD F9D2 F77D amdmi3@amdmi3.ru ..: jabber: amdmi3@jabber.ru http://www.amdmi3.ru From owner-freebsd-hardware@FreeBSD.ORG Fri Mar 15 10:29:21 2013 Return-Path: Delivered-To: freebsd-hardware@freebsd.org Received: from mx1.freebsd.org (mx1.FreeBSD.org [8.8.178.115]) by hub.freebsd.org (Postfix) with ESMTP id C45BE6F1 for ; Fri, 15 Mar 2013 10:29:21 +0000 (UTC) (envelope-from ipluta@wp.pl) Received: from mx3.wp.pl (mx3.wp.pl [212.77.101.7]) by mx1.freebsd.org (Postfix) with ESMTP id 5459D147 for ; Fri, 15 Mar 2013 10:29:20 +0000 (UTC) Received: (wp-smtpd smtp.wp.pl 15049 invoked from network); 15 Mar 2013 11:29:14 +0100 DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=wp.pl; s=1024a; t=1363343354; bh=gXGvvGDNw+6nXRO5QR1M07gxNbsoKFZbua4cQWWPUNQ=; h=From:To:Subject; b=teYXVcO9HjtriR+WSCXP1caszBvOQY3P3OCgtEC7PfS+iKO1uKSyteFkbUB1E19K4 4gPjI2CW4/o6a4YwC7WuxwgOjOQ5/u3wZEOgo9XXw1h+V38aflrdhq562YYr4vKP2a AM04Ni/dpeKlTNFZjIx/XsyQU0ik3BP/hK2r9GBM= Received: from aazp141.neoplus.adsl.tpnet.pl (HELO [10.0.0.207]) (ipluta@[83.6.153.141]) (envelope-sender ) by smtp.wp.pl (WP-SMTPD) with CAMELLIA256-SHA encrypted SMTP for ; 15 Mar 2013 11:29:14 +0100 Message-ID: <5142F7F1.5090308@wp.pl> Date: Fri, 15 Mar 2013 11:29:05 +0100 From: Ireneusz Pluta User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20130307 Thunderbird/17.0.4 MIME-Version: 1.0 To: freebsd-hardware@freebsd.org Subject: Re: FreeBSD compatible PCI-E SSD drives - current choices?
