<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>One of the nodes of a six node cluster got a hung process.
The ‘ps –elf’ command shows it as:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>5 D vtape 8542 1 6 77 0 - 77376 ocfs2_ Jan12

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The system isn’t hung, I can ssh into the system and
ls each ocfs2 directory. I have run the debugfs.ocfs2<o:p></o:p></p>
<p class=MsoNormal>command: debug.ocfs2 –R “stats” and it
shows no errors. I ran the ‘scanlocks2’ script and it didn’t
show<o:p></o:p></p>
<p class=MsoNormal>any hung locks. It did create some files (/tmp/_fsl_dm-22 <span
style='font-family:Wingdings'>ā</span> /tmp/_fsl_dm-26). The contents of those
files<o:p></o:p></p>
<p class=MsoNormal>are: “Debug string proto 2 found, but 1 is the
highest I understand.”<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any ideas on how to debug this ?<o:p></o:p></p>
