System was otherwise functional. There were no errors in the system logs or on the console and the raid adapter was fully function. Raw I/O to the disk devices (e.g. reads of the "c" partition of the disk that was wedged) remained fully functional during the event. Disk adapter is a 3ware 9650; firmware FE9x 4.08.00.006, driver 3.70.05.001, BBU enabled. It has no faults recorded against it or the drives attached to it. Looks like a race condition/deadlock of some sort in the mksnap_ffs code. The only unique "feature" of this event was that the disk in question was a DBMS storage RAID array and had a VERY large (many thousands of files) directory on it containing the log segments (typically ~1-2MB each, compressed, sequential log files numbering many thousand.) System was unable to be cleared; mksnap_ffs could not be killed and ultimately the machine had to be forcibly rebooted without a sync(). >How-To-Repeat: Attempting to replicate at this time. Will update the PR if I am able to do so. The subject machine had been up for more than six months at the time of the fault, and it has not reoccurred as of submission of this PR. Migration to 8.1 on this cluster is taking place, but I am going to put in a significant amount of time in attempting to replicate the problem on 8.0-STABLE (same kernel and binaries) on my test cluster to see if I can provoke the failure; I have an isolated environment in which I can make a decent attempt at recreating the event. >Fix: >Release-Note: >Audit-Trail: >Unformatted: From owner-freebsd-ia64@FreeBSD.ORG Tue Aug 3 11:17:26 2010 Return-Path: Delivered-To: freebsd-ia64@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id 279B81065673 for ; Tue, 3 Aug 2010 11:17:26 +0000 (UTC) (envelope-from mexas@bristol.ac.uk) Received: from dirj.bris.ac.uk (dirj.bris.ac.uk [137.222.10.78]) by mx1.freebsd.org (Postfix) with ESMTP id D6F1D8FC14 for ; Tue, 3 Aug 2010 11:17:25 +0000 (UTC) Received: from ncsd.bris.ac.uk ([137.222.10.59] helo=ncs.bris.ac.uk) by dirj.bris.ac.uk with esmtp (Exim 4.69) (envelope-from ) id 1OgFUo-0001Z1-1A; Tue, 03 Aug 2010 12:17:22 +0100 Received: from mech-cluster241.men.bris.ac.uk ([137.222.187.241]) by ncs.bris.ac.uk with esmtpsa (TLSv1:AES256-SHA:256) (Exim 4.67) (envelope-from ) id 1OgFUn-0001n6-7F; Tue, 03 Aug 2010 12:17:21 +0100 Received: from mech-cluster241.men.bris.ac.uk (localhost [127.0.0.1]) by mech-cluster241.men.bris.ac.uk (8.14.4/8.14.4) with ESMTP id o73BHL24043758; Tue, 3 Aug 2010 12:17:21 +0100 (BST) (envelope-from mexas@bristol.ac.uk) Received: (from mexas@localhost) by mech-cluster241.men.bris.ac.uk (8.14.4/8.14.4/Submit) id o73BHKgx043757; Tue, 3 Aug 2010 12:17:20 +0100 (BST) (envelope-from mexas@bristol.ac.uk) X-Authentication-Warning: mech-cluster241.men.bris.ac.uk: mexas set sender to mexas@bristol.ac.uk using -f Date: Tue, 3 Aug 2010 12:17:20 +0100 From: Anton Shterenlikht To: Peter Chubb Message-ID: <20100803111719.GA38040@mech-cluster241.men.bris.ac.uk> References: <20100730142039.GA10136@mech-cluster241.men.bris.ac.uk> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: User-Agent: Mutt/1.5.20 (2009-06-14) Cc: freebsd-ia64@freebsd.org Subject: Re: understanding EPIC X-BeenThere: freebsd-ia64@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Porting FreeBSD to the IA-64 List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 03 Aug 2010 11:17:26 -0000 On Sat, Jul 31, 2010 at 02:25:57PM +1000, Peter Chubb wrote: > >>>>> "Marcel" == Marcel Moolenaar writes: > > Marcel> On Jul 30, 2010, at 7:20 AM, Anton Shterenlikht wrote: > > > >> Also, is Gelato (aka IMPACT, OpenIMPACT - http://www.gelato.org, > >> http://gelato.uiuc.edu) dead? > > Marcel> Probably.
