Hi,
Steve is referring to a down-and-dirty tool that I wrote a while back
when gfs2 hangs were more common. Up to now it has just been sitting
on my hard drive and I dust it off if/when someone needs it. I'd like
to open-source the tool and add it to our public cluster git
repository, maybe as part of the gfs2-utils package.
Before I do that, I want to run it by Fabio ("The Godfather") Di Nitto
for some cleanups: the tool does some ugly things to accomplish its
goal and I don't want to wake up with a horse head in my bed!
Until then, I'd like to propose a naming contest. Right now I'm not
happy with the tool's name, which is currently "gfs2_hangalyzer".
Other names that have been suggested: gfs2_howsithangin, gfs2_anaglock
and gfs2_glocksmith. Let me know what you think.
Regards,
Bob Peterson
