That's awesome! :)

No, you would put the sleep at the start of obliterate-peer.sh on one
node only. If this works, would you be willing to test 'rhcs_fence' for
me? It's new, and could use some testing. It automatically adds a delay
based on the node's cluster ID, with no delay for the node with ID of "1".

If so, here is how to install it on both nodes;

wget -c https://raw.github.com/digimer/rhcs_fence/master/rhcs_fence
chmod 755 rhcs_fence
mv rhcs_fence /usr/sbin/

Then in drbd.conf, change:

outdate-peer "/sbin/obliterate-peer.sh";

to

outdate-peer "/usr/sbin/rhcs_fence";

Cheers. :)
