[sheepdog-users] collie node kill and md, something wrong

[Valerio Pachera]

Hi, after the successful test of cluster reweight of today, I tried
simply to kill one of the node.
Node 3 is the one started with a small disk and latered pluged the "big" disk.
I killed node 1, and after that, node 3 V-Nodes got the same value as
before the 'cluster rewight'
