A fabric which is originally created using the following command which specifies an min-port and the initial zookeeper-server-port ignores the min-port option when the fabric is resized:

fabric:create --clean --resolver localip --min-port 2183 --zookeeper-server-port 2183 --wait-for-provisioning

The ensemble is then resized and the following error occurs:

JBossFuse:karaf@root> fabric:ensemble-add rc2 rc3
This will change of the zookeeper connection string.
Are you sure want to proceed(yes/no):yes

Looking at the zookeeper.url property I see the zookeeper port is reset to port 2181:

JBossFuse:karaf@root> config:list | grep zookeeper.url
   zookeeper.url = 192.168.1.20:2181,rhpro.home:2182,:2181
JBossFuse:karaf@root>

For some other unknown reason one the hostnames also was not set.

Additionally, the containers should be using the localip resolver and this should cause all the URLs to use an IP address, but that doesn't appear to be the case either:

JBossFuse:karaf@root> fabric:container-resolver-list
[id]  [resolver]  [local hostname]  [local ip]    [public hostname]  [public ip]  [manual ip]
root  localip     rhpro.home        192.168.1.20                                             
rc1   localip     rhpro.home        192.168.1.20                                             
rc2   localip     rhpro.home        192.168.1.20      
rc3   localip     rhpro.home        192.168.1.20                                        
JBossFuse:karaf@root>

This also will destroy another fabric instance running on the same machine which is currently using port 2181.
