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