Carlson, Kais Belgaied, Mark Carl- son, Glenn Skinner. Product Approval Committee: Solaris PAC solaris-pac-opinion@sun.com 1. Summary This project adds ZFS booting capability to OpenSolaris, including ZFS-based Live Upgrade. 2. Decision & Precedence Information The project is approved as specified in references [1] and [2]. The project may be delivered in a minor release of Solaris via the ON and Install consolidations. 3.

Opinion 4.1. SPARC Versus x86 One member noted that several features (-B versus -Z, and -L) in the booting subsystem differ between SPARC and x86, and that this could confuse users. The project team pointed out that, for -B versus -Z, these two options are actually doing different things, though they happen to be used to accomplish the same goal for ZFS boot. The -L option is different because SPARC doesn't have GRUB. The committee members accepted the project team's explanation. 4.2. Swap Problems With ZFS Several members pointed out the deadlock problems with swap and ZFS. The project team committed to resolving those problems as a part of (or precondition to) the integration of this project. 4.3. Xen Support One member asked how Xen booting, which must extract the archive from ZFS early in the boot process, would work. The project team did not have an answer for this, but agreed to the stipulation that it must work, and any changes to that will require a subsequent review. 4.4. ZFS Dataset Naming The project team wished to change its special "BE" dataset container to be less LU-centric and use "ROOT" instead. The ARC members agreed, but one ARC member pointed out that it would be better to use an OS-reserved name space for this ZFS dataset, if possible. The project team agreed to inves- tigate this, but as we know of no such reservation, the ARC members agreed that using "ROOT" was sufficiently unlikely to cause trouble, given that it appears during initial install or during deliberate LU action. The reference PSARC/2006/370 Copyright 2008 Sun Microsystems - 3 - materials have been updated to use "ROOT," and any change from that will require a subsequent review. 5. Minority Opinion(s) None. 6. Advisory Information The project team is advised to investigate a reserved name space for ZFS datasets that have special meaning to the operating system, and use a reserved name to contain the boot environments. The project team is further advised to test Xen booting and verify proper operation with ZFS boot. 7. Appendices 7.1. Appendix A: Technical Changes Required None. 7.2.

Why is it just advice rather than a TCR to make sure that xVM boot doesn't break ? Advise can be ignored (not that I'm suggesing at all that the time would do that) and in this case that could cause breakage of another already integrated project. TCRs need to be very specific. I think in this case that is easy. xVM boot must work with a ZFS root. I wouldn't expect there to be any public interface changes to any of the xVM delivered install/boot commands for this to happen (given the "magic" is well hidden today). -- Darren J Moffat From casper@holland.sun.com Fri Jan 18 02:53:50 2008 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 m0IArnro025459 for ; Fri, 18 Jan 2008 02:53:49 -0800 (PST) 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 m0IArcCh026292 for <@sunmail2sca.sfbay.sun.com:PSARC-ext@Sun.COM>; Fri, 18 Jan 2008 18:53:48 +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 <0JUU0040369NFF00@brm-avmta-1.central.sun.com> for PSARC-ext@Sun.COM (ORCPT PSARC-ext@Sun.COM); Fri, 18 Jan 2008 03:53:47 -0700 (MST) Received: from dm-holland-02.uk.sun.com ([129.156.101.225]) by brm-avmta-1.central.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0JUU0008569MKM20@brm-avmta-1.central.sun.com> for PSARC-ext@Sun.COM (ORCPT PSARC-ext@Sun.COM); Fri, 18 Jan 2008 03:53:47 -0700 (MST) Received: from holland (room101.Holland.Sun.COM [10.16.117.40]) by dm-holland-02.uk.sun.com (8.13.6+Sun/8.13.6/ENSMAIL,v2.2) with ESMTP id m0IArjKq019648; Fri, 18 Jan 2008 10:53:45 +0000 (GMT) Date: Fri, 18 Jan 2008 11:53:45 +0100 From: Casper.Dik@sun.com Subject: Re: Opinion for review: 2006/370 ZFS Boot Support In-reply-to: <479080CA.1010407@Sun.COM> Sender: casper@holland.sun.com To: Darren J Moffat Cc: James Carlson , PSARC-ext@sun.com Message-id: <200801181053.m0IArjKq019648@dm-holland-02.uk.sun.com> MIME-version: 1.0 Content-type: text/plain; charset=us-ascii Content-transfer-encoding: 7BIT X-PMX-Version: 5.2.0.264296 References: <18319.48681.286801.509350@gargle.gargle.HOWL> <479080CA.1010407@Sun.COM> Status: RO Content-Length: 838 >James Carlson wrote: >> 6.

Two reasons: - We didn't vote to include a TCR as part of the case, so I can't just add it now without a new vote. - There's no known technical change to the project that's required to satisfy the constraint. > TCRs need to be very specific. I think in this case that is easy. xVM > boot must work with a ZFS root.

They do need to be specific, but it's more than that. They also need to be changes to the specification. There's no change to the specification of the project in this instance. A TCR essentially rewrites part of the project specification, and then allows the ARC members to vote on the modified specification. I don't see where we have such an issue. Casper.Dik@Sun.COM writes: > You can also ask why is the remark even there?

Project teams are responsible for making sure that they don't break anything, and doing any required testing to prove it. That's not an ARC issue -- it's a C-team review and development process issue. In this case, though, Tim Marsland noted during the project review that booting Xen instances is different, and the difference may have escaped the attention of the project team. The project team members agreed that they should talk with him, and make sure that Xen still works. Our assumption at this point is that the project as specified is complete and that no architectural changes will be required in order to make Xen work. If that's not the case, then the project team will need to file a new case in order to describe the required architectural changes. As best I can tell, the process worked exactly the way it was supposed to work, and the right things are happening.

I talked to Lin immediately after the meeting; I also discovered (on IRC) that the relevant work (on libfsimage and pygrub) was already in progress -- and so I think the dots are nicely connected. Please, no more time or neuronal activity on this until (as Jim said) additional architectural review is needed. tim From sac-owner Thu Jan 24 09:19:06 2008 Received: from phorcys.east.sun.com (phorcys.East.Sun.COM [129.148.174.143]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id m0OHJ5LB013110 for ; Thu, 24 Jan 2008 09:19:05 -0800 (PST) Received: from phorcys.east.sun.com (localhost [127.0.0.1]) by phorcys.east.sun.com (8.14.2+Sun/8.14.2) with ESMTP id m0OHJ5NI011911 for ; Thu, 24 Jan 2008 12:19:05 -0500 (EST) Received: (from carlsonj@localhost) by phorcys.east.sun.com (8.14.2+Sun/8.14.2/Submit) id m0OHJ55q011908; Thu, 24 Jan 2008 12:19:05 -0500 (EST) MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Message-ID: <18328.51336.905198.562430@gargle.gargle.HOWL> Date: Thu, 24 Jan 2008 12:19:04 -0500 From: James Carlson To: sac-review@sac.sfbay.sun.com Subject: Opinion for review: 2006/370 ZFS Boot Support X-Mailer: VM 7.01 under Emacs 21.3.1 Status: RO Content-Length: 6104 Please review this opinion, and submit any comments by 01/31/2008.

Opinion 4.1. SPARC Versus x86 One member noted that several features (-B versus -Z, and -L) in the booting subsystem differ between SPARC and x86, and that this could confuse users. The project team pointed out that, for -B versus -Z, these two options are actually doing different things, though they happen to be used to accomplish the same goal for ZFS boot. The -L option is different because SPARC doesn't have GRUB. The committee members accepted the project team's explanation. 4.2. Swap Problems With ZFS Several members pointed out the deadlock problems with swap and ZFS. The project team committed to resolving those problems as a part of (or precondition to) the integration of this project. 4.3. Xen Support One member asked how Xen booting, which must extract the archive from ZFS early in the boot process, would work. The project team did not have an answer for this, but agreed to the stipulation that it must work, and any changes to that will require a subsequent review. 4.4. ZFS Dataset Naming The project team wished to change its special "BE" dataset container to be less LU-centric and use "ROOT" instead. The ARC members agreed, but one ARC member pointed out that it would be better to use an OS-reserved name space for this ZFS dataset, if possible. The project team agreed to inves- tigate this, but as we know of no such reservation, the ARC members agreed that using "ROOT" was sufficiently unlikely to cause trouble, given that it appears during initial install or during deliberate LU action. The reference PSARC/2006/370 Copyright 2008 Sun Microsystems - 3 - materials have been updated to use "ROOT," and any change from that will require a subsequent review. 5. Minority Opinion(s) None. 6. Advisory Information The project team is advised to investigate a reserved name space for ZFS datasets that have special meaning to the operating system, and use a reserved name to contain the boot environments. The project team is further advised to test Xen booting and verify proper operation with ZFS boot. 7. Appendices 7.1. Appendix A: Technical Changes Required None. 7.2.

Using regular zfs mounts instead of legacy mounts for root requires two changes, one of which is a new interface: 1. The new interface is the new "noauto" value for the "canmount" dataset property, defined by this case. 2. Some changes are also required to the SMF start-up scripts (fs-root, fs-usr, and fs-local) to use zfs mounts instead of legacy mounts. This does not change any interface. These two changes will be integrated separately into Solaris from the rest of the zfs boot support. They are being integrated as fixes to CRs 6661070 (need canmount=noauto option for datasets to allow mount point to be set, but no mount done) and 6664570 (need support for canmount=noauto in smf scripts). These enhancements to zfs are necessary for Indiana and are not dependent on any other aspects of zfs boot support, and thus can be integrated separately.

Using regular zfs mounts instead of legacy mounts for root requires two changes, one of which is a new interface: 1. The new interface is the new "noauto" value for the "canmount" dataset property, defined by this case. 2. Some changes are also required to the SMF start-up scripts (fs-root, fs-usr, and fs-local) to use zfs mounts instead of legacy mounts. This does not change any interface. These two changes will be integrated separately into Solaris from the rest of the zfs boot support. They are being integrated as fixes to CRs 6661070 (need canmount=noauto option for datasets to allow mount point to be set, but no mount done) and 6664570 (need support for canmount=noauto in smf scripts). These enhancements to zfs are necessary for Indiana and are not dependent on any other aspects of zfs boot support, and thus can be integrated separately. Lori
