Licensing issue

kyawsoenaing — Sun, 15 Jan 2017 19:20:39 GMT

Hi,

I need some advise.

Currently I in mid of migration and getting license issue in 3 new index servers.
My environment as below.
Current splunk server are stand alone with all in one. New splunk servers implement as one master node and 3 indexers.
I have some servers data have been index to new 3 indexers.
Currently i have add the search peer at Current server to new 3 indexers.
I would like to assign license to new 3 indexers.
Current I have 2 licenses. First one is using in current server and second one is not using yet(for future used for DR server).

My question as below.
- Should I add license manager role to new master node server and add second license then create license pool to add current and 3 new indexers? After migration, I will put back first license.
- Should I add license manager role to new master node server and add second license then create license pool to add 3 new indexers?
- Should I create license pool at current server and add in current server and 3 new index servers?
-Any other way should I need to do?

Thank you.

Hi kyawsoenaing,

Please note that all cluster members must share:
- The same licensing pool
- The same licensing configuration
So, your cluster master and three indexers should be in the same licensing pool.
Also, Splunk recommends that you dedicate a host for each role, but you can enable multiple Splunk server roles - license master, deployer, deployment server - on a server with caveats.
I suggest the following license migration steps:
1. install a new Splunk instance on a server or VM as a dedicated license master. To add a license to a License Master, run:

splunk add licenses {path_to_license_file}

Switch the license master and three indexers to a license slave. Run this command on each slave.

splunk edit licenser-localslave -master_uri https://{Lic_Master:Mport}
To check the list of license slaves, run this command on the license master:

splunk list licenser-slaves

Of course, if you really want to also use the cluster master as a license master, I think you can, but it's not recommended. As to the second license, you can stack onto your first license on your license master.
Hope this helps. Thanks!
Hunter

Hi hunters,

Well, mostly for cluster master performance reasons. Actually, if you are planning a central license master, Splunk recommends that if you have a search head, you designate it as the license master. See details here: http://docs.splunk.com/Documentation/Splunk/6.5.1/Admin/Configurealicensemaster#Kinds_of_license_masters.
Thanks!
