[sheepdog] question about SBD

[Carl Hsieh]

Hi, I am playing with SBD (Version: 0.8.3-4):

# dog vdi list
  Name        Id    Size    Used  Shared    Creation time   VDI id  Copies  Tag
  test         0  1.0 GB  0.0 MB  0.0 MB 2016-01-25 14:36   7c2b25      3              


# echo "192.168.1.2 7000 test" > /sys/bus/sbd/add
-bash: echo: write error: Connection refused

Is there something I am missing?
There is no sheep daemon running under 192.168.1.2
Can someone help me to find out how to associate the vdi test to /dev/sdb ?
