Hi, I've been playing with smartmontools, and have had an error diagnosed by one of the selftest, and I'm hoping someone can provide some pointers as to what to do next... Quick summary - system is my main desktop, Debian Linux on x86, 4 SCSI disks set up using kernel software RAID-5. All the md devices are formatted with XFS. After running "smartctl -t long /dev/sdb", I get the following output from "smartctl -a /dev/sdb":- ======================================================= smartctl version 5.32 Copyright (C) 2002-4 Bruce Allen Home page is http://smartmontools.sourceforge.net/ Device: IBM DDYS-T18350N Version: S96H Serial number: 5EG73154 Device type: disk Transport protocol: Fibre channel (FCP-2) Local Time is: Thu Dec 23 12:16:29 2004 GMT Device supports SMART and is Enabled Temperature Warning Disabled or Not Supported SMART Health Status: OK Current Drive Temperature: 49 C Drive Trip Temperature: 85 C Manufactured in week 07 of year 2001 Current start stop count: 436 times Recommended maximum start stop count: 10000 times Error counter log: Errors Corrected Total Total Correction Gigabytes Total delay: [rereads/ errors algorithm processed uncorrected minor | major rewrites] corrected invocations [10^9 bytes] errors read: 0 0 4 8 48 24.088 40 write: 0 0 0 0 0 83.515 0 Non-medium error count: 0 SMART Self-test log Num Test Status segment LifeTime LBA_first_err [SK ASC ASQ] Description number (hours) # 1 Background long Failed in segment --> 5 3010 0x 2168629 [0x4 0x3e 0x3] ======================================================= My questions are:- 1/ How serious is this? Disk on way out now, or just a bad area? 2/ Can I map it out? 3/ How can I map the LBA address to a file? Things I've read make it clear how to answer 3/ for ext2 filesystems, but not XFS on RAID, and 5 minutes with the XFS debugger has not provided enough enlightenment yet... TIA, Mike. P.S. I'm not a list subscriber at the moment, so I'd really appreciate a CC on any replies. Thanks. |
