I have encountered a split brain scenario while following a tutorial.
I have been looking at the various options for the *after-sb-0pri*
parameter and have a couple of questions.  With some help from the
linux-ha list I now see that following the tutorials was not such a
good thing to do because the tutorials failed to mention anything
about split-brain, stonith, or fencing.  The next incarnation of my HA
cluster will use STONITH (ipmi) to help with the split brain
phenomenon.  I need to do some more work (learning) in this area but I
see that drbd has a parameter that deals with split brain recovery at
least at its own level.  My question to all is do I have to take into
consideration what I do in the HA world (Stonith etc) when I set the
*after-sb-0pri* parameter or are the two non intersecting?
