Splunk 6.2 Cluster - Message - Duplicate instance name. Ensure each instance has a unique instance (host) name.

[eichfuss]

Hi there,

i run into a problem with the new Distributed Management Console. When i change to the Ditributed Mode in the Setup view, i get the following Error Message:

Duplicate instance name. Ensure each
instance has a unique instance (host)
name.

Instance (host)--------Instance (serverName)----------Machine

steve.xxxx.de----------bill.xxxx.de--------------------------bill.xxxx.de

steve.xxxx.de----------mike.xxxx.de--------------------------mike.xxxx.de

So steve is the ClusterMaster and the two Nodes are bill and mike. I have no idea where my mistake is. Hope anyone can give me a hint.

Thanks
Regards, Sven

Make sure both server name and host have unique values (looks like you have two instances with the same host value).

From documentation:

"Make sure that each instance in the deployment (each search head, license master, and so on) has a unique server.conf serverName value and inputs.conf host value."

the 'serverName's all need to be different, as well as the GUID (in splunk/etc/instance.cfg)

oops, sorry. I had a mistake in my post. of course i have a Indexer with servername "bill" and one indexer "mike" and the clustermaster "steve" all have different servernames and guid.

It looks like both of your "bill" and "mike" instances have the same host value in inputs.conf ("steve.xxxx.de). Those have to be unique as well.
