Hi Joel, thanks for the answer...
OK, but i'm not sure about a kernel oops being executed.
I'd change panic_on_oops to 0 and it work "as expected" (well, you
will see that I wasnt totally sincere about my setup. I'm using RHCS
and gfs too :X)
Here is the paste of /var/log/messages from the remaining node
(panic_on_oops=0) when I turn off the fiber switch for primary path.
