Hi there,
Have been messing with ELK for a few months now, and finally getting around to deploying.
being that i wish to use the server in production, with nodes for SSD/HDD I'm due to expand out of the single VM.
So, spun up the new machines to load my data nodes on, started setting things up.
Struck me once i changed the existing node with about 30GB of data, soon as i change the Cluster.name, the data is gone.
Now logic says, quick google to the rescue! - it would seem the clustername in the data folder was removed as of 5.x https://www.elastic.co/guide/en/elasticsearch/reference/current/_path_to_data_on_disk.html
At this point I'm stuck wondering, do i just roll with the default name and cringe just a little, do i migrate data then migrate back to the intended master/ingest?
I must note, before anyone jumps to it... Stack is purely used within the home, server monitoring, modem monitoring etc
Any ideas on changing the name would be appreciated
