============================================================================

 

One of the nodes of a six node cluster got a hung process. The  'ps -elf' command shows it as:

 

5 D  vtape     8542     1  6  77   0 - 77376 ocfs2_ Jan12 ?        01:34:31 /opt/bti/mas/bin/vt -d -p /var/run/vt.pid

 

The system isn't hung, I can ssh into the system and ls each ocfs2 directory. I have run the debugfs.ocfs2

command:  debug.ocfs2 -R "stats"   and it shows no errors. I ran the 'scanlocks2' script and it didn't show

any hung locks. It did create some files (/tmp/_fsl_dm-22 à /tmp/_fsl_dm-26). The contents of those files

are:  "Debug string proto 2 found, but 1 is the highest I understand."

 

Any ideas on how to debug this ?

 

Thanks,

 

charlie
