Um, I get you wrong. On my box I couldn't reproduce it. Maybe you can
try my v6 patch set.

I used following script:

for i in 0 1 2; do sheep/sheep -d /home/tailai.ly/sheepdog/store/$i -z
$i -p 700$i;sleep 1;done
collie/collie cluster format $1
qemu-img create -f raw sheepdog:test 128G
collie/collie cluster snapshot
collie/collie cluster snapshot -l
collie/collie cluster snapshot -R 1


Thanks,
Yuan
