It appears that the "ostdb-7" file is cut off, but that may just be due to the way the output is logged.</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>lfsck -c -l --mdsdb /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/mdsdb --ostdb /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-0 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-1 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-2 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-3 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-4 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-5 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-6 /mnt/lustre 06:03:09:lfsck 1.41.90.wc4 (01-Sep-2011) 06:03:10:/home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/mdsdb:mdshdr 06:03:10:: Invalid argument 06:03:10:/usr/lib64/lustre/tests/test-framework.sh: line 2772: 8975 Segmentation fault lfsck -c -l --mdsdb /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/mdsdb --ostdb /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-0 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-1 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-2 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-3 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-4 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-5 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-6 /mnt/lustre 06:03:10: lfsck : @@@@@@ FAIL: lfsck -c -l --mdsdb /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/mdsdb --ostdb /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-0 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-1 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-2 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-3 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-4 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-5 /home/autotest/shared_dir/2012-04-07/230543-7f46bd3a7040/ostdb-6 /mnt/lustre returned 139, should be &lt;= 1 06:03:11:Dumping lctl log to /logdir/test_logs/2012-04-07/lustre-master-el6-x86_64-el5-x86_64__479__-7f46bd3a7040/lfsck..*.1333879390.log 06:03:15:lfsck returned 0 </pre> </div></div> &nbsp;&nbsp;&nbsp;&nbsp;* jenkins-arch=x86_64,build_type=server,distro=el6,ib_stack=inkern (x86_64)<br/> &nbsp;&nbsp;&nbsp;&nbsp;* jenkins-arch=x86_64,build_type=client,distro=el5,ib_stack=inkern (x86_64) LU-1294

Segmentation fault running lfsck

Bug Blocker Resolved Duplicate Sarah Liu Maloo Mon, 9 Apr 2012 16:14:01 +0000 Tue, 10 Apr 2012 12:35:31 +0000 Mon, 9 Apr 2012 23:55:28 +0000 Lustre 2.3.0 0 2 <p>TT-487 is to track automated collection of core dumps, but until that is finished this test needs to be run by hand and a core file attached to this bug and/or run lfsck under gdb and collect the stack trace.</p> <p>The client and server are running different versions - RHEL5 on the client and RHEL6 on the server. This may be the root cause of the problem, since db4 is not a very portable database format. Typically this is not a problem for lfsck, since the databases are only useful for a very short time.</p> <p>Sarah</p> <p>Could you please try and reproduce this failure and gather fuller data?</p> <p>Thanks</p> <p>Peter</p> <p>duplicate of <a href="https://jira.whamcloud.com/browse/LU-1096" title="Test failure on test suite lfsck,Segmentation fault" class="issue-link" data-issue-key="LU-1096"><del>LU-1096</del></a></p> <p>(gdb) run -c -l --mdsdb /scratch/mdsdb --ostdb /scratch/ostdb-0 /mnt/lustre<br/> Starting program: /usr/sbin/lfsck -c -l --mdsdb /scratch/mdsdb --ostdb /scratch/ostdb-0 /mnt/lustre<br/> warning: no loadable sections found in added symbol-file system-supplied DSO at 0x2aaaaaaab000<br/> <span class="error">&#91;Thread debugging using libthread_db enabled&#93;</span><br/> lfsck 1.41.90.wc4 (01-Sep-2011)<br/> /scratch/mdsdb:mdshdr<br/> : Invalid argument</p> <p>Program received signal SIGSEGV, Segmentation fault.<br/> 0x0000003d9e478480 in strlen () from /lib64/libc.so.6<br/> (gdb) bt<br/> #0 0x0000003d9e478480 in strlen () from /lib64/libc.so.6<br/> #1 0x0000003d9e446aae in vfprintf () from /lib64/libc.so.6<br/> #2 0x0000003d9e4e6ae7 in __vfprintf_chk () from /lib64/libc.so.6<br/> #3 0x0000000000403dd9 in log_write (fmt=0x40f950 "%s: error opening mds_hdr in %s: rc %d\n") at lfsck.c:231<br/> #4 0x0000000000406038 in lfsck_run_checks () at lfsck.c:1849<br/> #5 0x00000000004061d7 in main (argc=8, argv=0x7fffffffe918) at lfsck.c:2077<br/> (gdb) </p> Related Development Rank 1|hzvh3r: Rank (Obsolete) 6420 Severity
