Date: Wed, 02 Feb 2011 08:30:56 -0500 Message-ID: Mime-Version: 1.0 Reply-To: mlueck@lueckdatasystems.com List-Id: XFS Filesystem from SGI List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset="us-ascii"; Format="flowed" Sender: xfs-bounces@oss.sgi.com Errors-To: xfs-bounces@oss.sgi.com To: linux-xfs@oss.sgi.com Greetings, Somehow a reported IRIX bug with XFS got into Ubuntu 10.04 (Lucid) starting with kernel 2.6.32-27. I am cross posting to this list in order to receive details as to what bug got in Ubuntu which has been solved in IRIX, hoping with more details Ubuntu might make the same fix. Ubuntu has since updated their kernel to 2.6.32-28 and someone already verified at the bug report that the problem persists with that kernel version. "Regression between 2.6.32-27 and 2.6.32-26 xfsdump SGI_FS_BULKSTAT errno = 22" https://bugs.launchpad.net/bugs/692848 On our Ubuntu 10.04 LTS server running x86 code, this evening a kernel update was ready for installation. I updated the kernel, rebooted (IPL'ed), and proceeded with the backup which utilized xfsdump as we use the xfs filesystem. Four of the xfsdump received a never before seen error: SGI_FS_BULKSTAT errno = 22 Output as follows: using file dump (drive_simple) strategy version 3.0.4 (dump format 3.0) - Running single-threaded level 0 dump of ldslnx01:/srv dump date: Mon Dec 20 21:59:33 2010 session id: f98f8cc0-963f-41a6-9a19-a89192502bf0 session label: "data" ino map phase 1: constructing initial dump list ino map phase 2: skipping (no pruning necessary) ino map phase 3: skipping (only one dump stream) ino map construction complete estimated dump size: 100739707392 bytes WARNING: no media label specified creating dump session media file 0 (media 0, file 0) dumping ino map dumping directories SGI_FS_BULKSTAT failed: Invalid argument (22) dump size (non-dir files) : 0 bytes NOTE: dump interrupted: 79 seconds elapsed: may resume later using -R option Dump Status: INTERRUPT This backup file did have some size to it. The other three, backing up smaller amounts of data, were all zero (0) length dump files. I rebooted to the prior kernel: $ uname -a Linux ldslnx01 2.6.32-26-generic-pae #48-Ubuntu SMP Wed Nov 24 10:31:20 UTC 2010 i686 GNU/Linux And the same backup gets to 100% success. Reboot to the new kernel, same failure. I think that fairly well illustrates that the problem exists only with the kernel update installed this evening. <><><><> I did come across a reference to this problem on the SGI website: http://techpubs.sgi.com/library/tpl/cgi-bin/getdoc.cgi?coll=0650&db=relnotes&fname=/usr/relnotes/eoe 1.6.17 Bugs fixed in IRIX 6.5.13 + 816457: xfsdump SGI_FS_BULKSTAT errno = 22 cxfs So evidently it is something that has been seen and corrected in IRIX. -- Michael Lueck Lueck Data Systems http://www.lueckdatasystems.com/ _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
