--- Comment #6 from Dustin Black <dblack at redhat.com> ---
For my original reproducer, if I insert the cache drop where I logically think
it should go in step 5:

5. Correct the network split and stat the file from the client:

#!/bin/bash
exe() { echo "\$ $@" ; "$@" ; }

if [ $HOSTNAME == "n1" ]; then
   echo "Correcting network split with iptables..."
   exe iptables -F OUTPUT
   echo "Dropping caches due to BZ 1229226..."
   echo 3 > /proc/sys/vm/drop_caches
   echo "Statting file002 to induce heal..."
   exe stat /rhgs/client/rep01/file002
else
   echo "Wrong host!"
fi


It does _not_ correct the problem.

It also doesn't help if I put the cache drop in step 2 just after modifying the
file.
