My primary concern is the default state of RMW as an error. My concerns are that an error return by default is inappropriate. I understand the concerns of the project that serious performance concerns may go undetected without the error return by default. Array manufacturers also are subject to this penalty, if the physical I/O is mis-aligned. The default behavior for arrays does not appear to be a fatal error. An alternate proposal would be a "multi-state" RMW flag. I'd propose a "warning only" mode as the default, and "return error on RMW" and "do not report RMW conditions" as other potential settings. Having this state be a "global" setting would also seem to be overdone. A system-wide setting seems too much, and a "per-disk" setting also seems the wrong granularity. Setting this on a "per disk partition" would seem to be adequate. Having a global that takes precedence over the per partition would also be acceptable, in my opinion. Please consider these issues. -- --------------------------------------------------------------------- Rick Matthews email: Rick.Matthews@sun.com Sun Microsystems, Inc. phone:+1(651) 554-1518 1270 Eagan Industrial Road phone(internal): 54418 Suite 160 fax: +1(651) 554-1540 Eagan, MN 55121-1231 USA main: +1(651) 554-1500 --------------------------------------------------------------------- From Larry.Liu@sun.com Sun Mar 15 19:36:43 2009 Received: from sunmail5.uk.sun.com (sunmail5.UK.Sun.COM [129.156.85.165]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id n2G2ahTs001139 for ; Sun, 15 Mar 2009 19:36:43 -0700 (PDT) Received: from nwk-avmta-2.sfbay.sun.com (nwk-avmta-2.SFBay.Sun.COM [129.145.155.6]) by sunmail5.uk.sun.com (8.13.8+Sun/8.13.8/ENSMAIL,v2.2) with ESMTP id n2G2aYBi016378 for <@sunmail2sca.sfbay.sun.com:psarc-ext@sun.com>; Mon, 16 Mar 2009 02:36:42 GMT Received: from pmxchannel-daemon.nwk-avmta-2.sfbay.sun.com by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) id <0KGK00507V93MA00@nwk-avmta-2.sfbay.sun.com> for psarc-ext@sun.com (ORCPT psarc-ext@Sun.COM); Sun, 15 Mar 2009 19:36:39 -0700 (PDT) Received: from sineb-mail-2.sun.com ([192.18.19.7]) by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0KGK0009CV92ZB30@nwk-avmta-2.sfbay.sun.com> for psarc-ext@sun.com (ORCPT psarc-ext@Sun.COM); Sun, 15 Mar 2009 19:36:39 -0700 (PDT) Received: from fe-apac-06.sun.com (fe-apac-06.sun.com [192.18.19.177] (may be forged)) by sineb-mail-2.sun.com (8.13.6+Sun/8.12.9) with ESMTP id n2G2aceI001748 for ; Mon, 16 Mar 2009 02:36:38 +0000 (GMT) Received: from conversion-daemon.mail-apac.sun.com by mail-apac.sun.com (Sun Java(tm) System Messaging Server 7.0-5.01 64bit (built Feb 19 2009)) id <0KGK00C00V5SKC00@mail-apac.sun.com> for psarc-ext@Sun.COM (ORCPT psarc-ext@Sun.COM); Mon, 16 Mar 2009 10:36:38 +0800 (SGT) Received: from [129.150.32.187] ([unknown] [129.150.32.187]) by mail-apac.sun.com (Sun Java(tm) System Messaging Server 7.0-5.01 64bit (built Feb 19 2009)) with ESMTPSA id <0KGK00F1QV8QJR30@mail-apac.sun.com> for psarc-ext@Sun.COM (ORCPT psarc-ext@Sun.COM); Mon, 16 Mar 2009 10:36:37 +0800 (SGT) Date: Mon, 16 Mar 2009 10:36:31 +0800 From: Larry Liu Subject: Re: PSARC 2008/769 - Multiple disk sector size support In-reply-to: <49BA794D.7020506@Sun.COM> Sender: Larry.Liu@sun.com To: Rick Matthews Cc: Mark Carlson , psarc-ext@sun.com Message-id: <49BDBB2F.3040606@sun.com> MIME-version: 1.0 Content-type: multipart/mixed; boundary="Boundary_(ID_PYLzRMoELyQ+sqDaOEu1zw)" X-PMX-Version: 5.4.1.325704 References: <49BA794D.7020506@Sun.COM> User-Agent: Thunderbird 2.0.0.19 (Windows/20081209) Status: RO Content-Length: 4734 This is a multi-part message in MIME format. --Boundary_(ID_PYLzRMoELyQ+sqDaOEu1zw) Content-type: text/plain; format=flowed; charset=UTF-8 Content-transfer-encoding: 8BIT Hi Rick, Thanks for your suggestion. We made the changes accordingly. That said, by default, sd(7D) will do RMW to misaligned I/O with warning message. Custormers can configure the behavior as do RMW without warning message and do not do RMW with error returned. The configuration will be per device based (PSARC 2008/465 [s]sd-config-list). We don't have a mechanism to configure the behavior per partition based. I attached the modified rmw design doc.

However, customers could configure sd to not do RMW or do RMW without reporting warning message. 3.6.2 Design Specification There are two key elements which describe each I/O. One is the size of the I/O, the other is the starting block number. If the I/O size is indivisible by physical sector size, or the start block number is indivisible by the quotient of physical sector size and logical block size, we call it misaligned I/O. 3.6.2.1 Basic operation If I/O requests which are aligned with the physical sector size of the disk are sent to sd(7D), they will be transmitted directly; If they are misaligned, they will be transmitted through RMW with warning message on console. Error message looks like "I/O reqest is not aligned with %d disk sector size. It is transmitted through Read Modify Write but the performance is very low.\n" 3.6.2.2 Configuration in sd.conf Customers can edit [s]sd-config-list in sd.conf to configure the behavior for the given device when handling misaligned I/O. rmw-type Committed UINT32 #define SD_RMW_TYPE_DEFAULT 0 /* do rmw with warning message */ #define SD_RMW_TYPE_NO_WARNING 1 /* do rmw without warning message */ #define SD_RMW_TYPE_RETURN_ERROR 2 /* do not do rmw and return error */ The default value is set to 0 which means do RMW with warning message. EINVAL is chosen as the returning value when rmw-type is configured as 1. This value is in concordance of the returning value of sd(a)read/sd(a)write when I/O is misaligned. 3.6.2.4 Console message If every RMWed I/O because of misaligned request triggers one console message, there could be too many of them which cause debug messages flooding. An event driven timer controlled console message mechanism is proposed. The first misaligned I/O will triggers a console message and a timer (say 10 seconds). The succeeding misaligned I/O will not triger console message until the timer is timeout. And while logging the console message, a new timer will be started. Now the console message will contain the number of RMWed I/O, say "%d I/O reqests are not aligned with %d disk sector size. they are transmitted through Read Modify Write but the performance is very low.\n" --Boundary_(ID_PYLzRMoELyQ+sqDaOEu1zw)-- From Richard.Matthews@sun.com Mon Mar 16 09:44:02 2009 Received: from sunmail4.singapore.sun.com (sunmail4.Singapore.Sun.COM [129.158.71.19]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id n2GGi1cQ029920 for ; Mon, 16 Mar 2009 09:44:02 -0700 (PDT) Received: from brm-avmta-1.central.sun.com (brm-avmta-1.Central.Sun.COM [129.147.4.11]) by sunmail4.singapore.sun.com (8.13.4+Sun/8.13.3/ENSMAIL,v2.2) with ESMTP id n2GGhsVa016058 for <@sunmail2sca.sfbay.sun.com:psarc-ext@sun.com>; Tue, 17 Mar 2009 00:44:00 +0800 (SGT) Received: from pmxchannel-daemon.brm-avmta-1.central.sun.com by brm-avmta-1.central.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) id <0KGL0000FYHAB600@brm-avmta-1.central.sun.com> for psarc-ext@sun.com (ORCPT psarc-ext@Sun.COM); Mon, 16 Mar 2009 10:43:58 -0600 (MDT) Received: from brmea-mail-2.sun.com ([192.18.98.43]) by brm-avmta-1.central.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0KGL00I86YHAAI60@brm-avmta-1.central.sun.com> for psarc-ext@sun.com (ORCPT psarc-ext@Sun.COM); Mon, 16 Mar 2009 10:43:58 -0600 (MDT) Received: from fe-amer-10.sun.com ([192.18.109.80]) by brmea-mail-2.sun.com (8.13.6+Sun/8.12.9) with ESMTP id n2GGhwsS002504 for ; Mon, 16 Mar 2009 16:43:58 +0000 (GMT) Received: from conversion-daemon.mail-amer.sun.com by mail-amer.sun.com (Sun Java(tm) System Messaging Server 7.0-5.01 64bit (built Feb 19 2009)) id <0KGL00J00VA4L600@mail-amer.sun.com> for psarc-ext@Sun.COM (ORCPT psarc-ext@Sun.COM); Mon, 16 Mar 2009 10:43:58 -0600 (MDT) Received: from Rick-Matthews-MacBook-Pro-15.local ([unknown] [129.150.34.151]) by mail-amer.sun.com (Sun Java(tm) System Messaging Server 7.0-5.01 64bit (built Feb 19 2009)) with ESMTPSA id <0KGL00CG9YGQK4E0@mail-amer.sun.com> for psarc-ext@Sun.COM (ORCPT psarc-ext@Sun.COM); Mon, 16 Mar 2009 10:43:39 -0600 (MDT) Date: Mon, 16 Mar 2009 11:43:40 -0500 From: Rick Matthews Subject: Re: PSARC 2008/769 - Multiple disk sector size support In-reply-to: <49BDBB2F.3040606@sun.com> Sender: Richard.Matthews@sun.com To: Larry Liu Cc: Mark Carlson , psarc-ext@sun.com Message-id: <49BE81BC.1070907@Sun.COM> MIME-version: 1.0 Content-type: text/plain; format=flowed; charset=UTF-8 Content-transfer-encoding: 7BIT X-PMX-Version: 5.4.1.325704 References: <49BA794D.7020506@Sun.COM> <49BDBB2F.3040606@sun.com> User-Agent: Thunderbird 2.0.0.19 (Macintosh/20081209) Status: RO Content-Length: 1041 Larry Liu wrote: > Hi Rick, > > Thanks for your suggestion.
