[sheepdog-users] dog node recovery and node with single nic

[Valerio Pachera]

Hi, I added a node to my testing cluster (id 2).
This node has a single nic, the other have two (one dedicated to sheepdog
sync).

root at test006:~/script# dog node list
  Id   Host:Port         V-Nodes       Zone
   0   192.168.2.44:7000        71  738371776
   1   192.168.2.45:7000        71  755148992
   2   192.168.2.46:7000        289  771926208
   3   192.168.2.47:7000        81  788703424

Dog node recovery shows the right output from all nodes but the new one:
