[sheepdog-users] Single-node sheepdog for testing

[Scott Devoid]

Thanks Hitoshi,

So I am seeing some interesting behavior when I try to shutdown and restart
my 3 node cluster:

$ for pid in `pgrep | sheep`; do kill -15 $pid; sleep 2; done
$ for i in 0 1 2; do sheep -c local -d /path/to/store/$i -z $i -p 700$i;
sleep 1; done

Shutdown works fine, but when I go to start the cluster up the first member
fails when the second joins. I think this is because the second member has
a later epoch than the first.

Here is the tail of the first member logs:

Let me know if I am doing things incorrectly.

Thanks,
~ Scott
