Correct.  The short answer is that the code guesses what is the most likely 
private ipv4 network shared by all hosts.  If there is more than one, then 
pick the top two (knowing this won't work for everyone, but I haven't heard as 
many complaints as anticipated.)

It's a sanity check.  All ceph nodes need an interface on the public network.  
All storage nodes need an interface on the cluster network.  So, first 
question:  is 192.168.151.0/24 a suitable cluster network?  If so, the query 
to Salt about osd02 seems to think that no address in that subnet is assigned 
to any interface on that minion.

Take a look at 

salt 'osd02*' grains.items

Reconcile that output (you'll notice a few stanzas related to addresses) 
against ifconfig/ip.

Hope that helps.
