hi @PickleRick , First of all, Thank you so much for your time ! I am upgrading my Indexer Cluster first.. all are windows server 2016. Before update when i login to my Indexer cluster:Master node console i can see 2 peer nodes (HostA and HostB) under Peer tab and under Search Heads i see one HostC. I was simply running the installed for Splunk Enterprise 8.1 on one of Peer hostA and rebooted the server upon complete installation. After that when i go back to Master node HostC and open the indexer Clustering console , it is not showing the HostA under Peer tab. seems it is not able to join back the peer.. also not sure what is the best way to do this update... I simply followed the Splunk upgrade guide which seems quite simple but indeed reality is different..LOL. let me know if you need any further information. Thank u !
