It looks that you meet with a kernel panic. Strange. So do you umount 
the volume before running tunefs.ocfs2? We have never meet with it 
before. Could you please file a bug in http://oss.oracle.com/bugzilla/ 
about this. Thanks.
The good thing is that it corrupts in dlmfs, so your data should be ok.
