I have several FreeBSD boxes with UFS2 and soft-updates enabled (no SU+J) mounted as (ufs, local, soft-updates). They periodically run dump(8) to make zero-level backups once a week and first level incremental backup on other = days of week. The command line is like: dump -$level -C 32 -h 0 -au -f - /home That is, not snapshots used and cache size is big. Sometimes it finished just fine. Sometimes it its four children start to eat CPU at max and loop forever not making progress and never finishing until killed manually. I've rebuilt /sbin/dump with debugging options -O0 -g and installed unstrip= ped binary and when the problem reproduced, I ran sysctl kern.corefile=3D/var/tmp/%N.%P.core && killall -QUIT dump. So, I have five = core files with debug info. I've digged it a bit and I think I found the problem. Here is what do I get= for FreeBSD 11.1-STABLE/amd64 r332356 and file system having 41943040 sectors, = 512 bytes per sector and standard bsize=3D32768, fsize=3D4096: Core was generated by `dump: /dev/mirror/gm0s1g: pass 4: 60.53% done, finis= hed in 0:03 at Fri May 11 03'.

If so, is it possible that the fi= le causing the problem is being written at the time that dump is trying to dump it? If so, then dump may read it in an inconsistent state (e.g., it has allocated, but not yet initialised one of its indirect blocks (hence the garbage value to see when it reads the not-yet initialised block. The reason for dumping a snapshot is to ensure that you get a consistent view of the filesystem. --=20 You are receiving this mail because: You are on the CC list for the bug.= From owner-freebsd-fs@freebsd.org Sat May 12 08:39:13 2018 Return-Path: Delivered-To: freebsd-fs@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 86E6BFCD14F for ; Sat, 12 May 2018 08:39:13 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mailman.ysv.freebsd.org (mailman.ysv.freebsd.org [IPv6:2001:1900:2254:206a::50:5]) by mx1.freebsd.org (Postfix) with ESMTP id 1D8E4847F7 for ; Sat, 12 May 2018 08:39:13 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: by mailman.ysv.freebsd.org (Postfix) id D307BFCD14E; Sat, 12 May 2018 08:39:12 +0000 (UTC) Delivered-To: fs@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id C1C9CFCD14D for ; Sat, 12 May 2018 08:39:12 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.ysv.freebsd.org (mxrelay.ysv.freebsd.org [IPv6:2001:1900:2254:206a::19:3]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client CN "mxrelay.ysv.freebsd.org", Issuer "Let's Encrypt Authority X3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 568EC847D8 for ; Sat, 12 May 2018 08:39:12 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2001:1900:2254:206a::16:76]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mxrelay.ysv.freebsd.org (Postfix) with ESMTPS id AA73015667 for ; Sat, 12 May 2018 08:39:11 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id w4C8dBSJ047382 for ; Sat, 12 May 2018 08:39:11 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id w4C8dBax047380 for fs@FreeBSD.org; Sat, 12 May 2018 08:39:11 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: www set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: fs@FreeBSD.org Subject: [Bug 228174] [dump] dump(8) can read garbage and loop forever Date: Sat, 12 May 2018 08:39:11 +0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: bin X-Bugzilla-Version: 11.1-STABLE X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: eugen@freebsd.org X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: stable@FreeBSD.org X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: https://bugs.freebsd.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-BeenThere: freebsd-fs@freebsd.org X-Mailman-Version: 2.1.25 Precedence: list List-Id: Filesystems List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 12 May 2018 08:39:13 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D228174 --- Comment #2 from Eugene Grosbein --- (In reply to Kirk McKusick from comment #1) Yes, this is mounted and live file system and files are created here. Does UFS2+SU snapshot guarantee that dump won't get uninitialized indirecti= on blocks from the file system if snapshot creation occurs at same moment? I still believe dump should not loop forever and should perform some sanity checks on indirection blocks. --=20 You are receiving this mail because: You are on the CC list for the bug.=
