Template Version: @(#)sac_nextcase 1.68 02/23/09 SMI This information is Copyright 2009 Sun Microsystems 1. Introduction 1.1. Project/Component Working Name: zpool split 1.2. Name of Document Author/Supplier: Author: Mark Musante 1.3 Date of This Document: 24 September, 2009 4. Technical Description OVERVIEW: Some practices in data centers are built around the use of a volume manager's ability to clone data. An administrator will attach a set of disks to mirror an existing configuration, wait for the resilver to complete, and then physically detach and remove those disks to a new location. Currently in zfs, the only way to achieve this is by using zpool offline to disable a set of disks, zpool detach to permanently remove them after they've been offlined, move the disks over to a new host, zpool force-import of the moved disks, and then zpool detach the disks that were left behind. This is cumbersome and prone to error, and even then the new pool cannot be imported on the same host as the original. PROPOSED SOLUTION: Introduce a "zpool split" command. This will allow an administrator to extract one disk from each mirrored top-level vdev and use them to create a new pool with an exact copy of the data. The new pool can then be imported on any machine that supports that pool's version.

I suppose that giving a device specification (i.e. list of devices) means that exactly those devices will be split off and you have to list all devices if you specify any? Perhaps this should be made explicit? Otherwise, great feature.

Is the split-off disk set a one-side of a new mirror or just a non-redundant pool? 2. Can you split the mirror into two 2-way or multiway mirrors, leaving the original multiway mirror non-compromised? This would save time for resilvering of a split-off disk set if a new mirror is needed. The following practice could be a best way to avoid compromising the original mirrored pool and creating split-off mirror: 1. Attach a new set of disks to a mirrored pool, a new set being sufficient for at least a 2-way mirror 2. Create a 4-way (or more way) mirror 3. Resilver attached disk set 4 Split resulting mirror into 2 mirror Is it possible with your proposal? -Pawel From tim.haley@sun.com Wed Sep 30 10:08:00 2009 Received: from newsunmail1brm.central.sun.com (newsunmail1brm.Central.Sun.COM [129.147.62.245]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id n8UH80Cb023106 for ; Wed, 30 Sep 2009 10:08:00 -0700 (PDT) Received: from nwk-avmta-1.SFBay.Sun.COM (nwk-avmta-1.SFBay.Sun.COM [129.146.11.74]) by newsunmail1brm.central.sun.com (8.13.7+Sun/8.13.7/ENSMAIL,v2.2) with ESMTP id n8UH7wn2045997; Wed, 30 Sep 2009 11:07:59 -0600 (MDT) Received: from pmxchannel-daemon.nwk-avmta-1.sfbay.Sun.COM by nwk-avmta-1.sfbay.Sun.COM (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) id <0KQS00E0HNLA6I00@nwk-avmta-1.sfbay.Sun.COM>; Wed, 30 Sep 2009 10:07:58 -0700 (PDT) Received: from brmea-mail-4.sun.com ([192.18.98.36]) by nwk-avmta-1.sfbay.Sun.COM (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0KQS0058XNL97TA0@nwk-avmta-1.sfbay.Sun.COM>; Wed, 30 Sep 2009 10:07:57 -0700 (PDT) Received: from fe-amer-10.sun.com ([192.18.109.80]) by brmea-mail-4.sun.com (8.13.6+Sun/8.12.9) with ESMTP id n8UH7vPq019150; Wed, 30 Sep 2009 17:07:57 +0000 (GMT) Received: from conversion-daemon.mail-amer.sun.com by mail-amer.sun.com (Sun Java(tm) System Messaging Server 7u2-7.04 64bit (built Jul 2 2009)) id <0KQS00600NDN8V00@mail-amer.sun.com>; Wed, 30 Sep 2009 11:07:57 -0600 (MDT) Received: from [172.20.25.27] ([unknown] [172.20.25.27]) by mail-amer.sun.com (Sun Java(tm) System Messaging Server 7u2-7.04 64bit (built Jul 2 2009)) with ESMTPSA id <0KQS001Y5NL2RS90@mail-amer.sun.com>; Wed, 30 Sep 2009 11:07:55 -0600 (MDT) Date: Wed, 30 Sep 2009 11:07:50 -0600 From: Tim Haley Subject: Re: zpool split [PSARC/2009/511 FastTrack timeout 10/31/2009] In-reply-to: <200909242123.n8OLNmlf020732@spidey.local> Sender: Timothy.Haley@sun.com To: PSARC-ext@sun.com Cc: zfs-team@sun.com Message-id: <4AC39066.9060509@sun.com> MIME-version: 1.0 Content-type: text/plain; CHARSET=US-ASCII; format=flowed Content-transfer-encoding: 7BIT X-PMX-Version: 5.4.1.325704 References: <200909242123.n8OLNmlf020732@spidey.local> User-Agent: Thunderbird 2.0.0.22 (X11/20090909) Status: RO Content-Length: 50 This case was approved in today's meeting. -tim
