Sorry this could be a very basic. I am running ES 7 cluster with 3 servers. All 3 servers have data and one of them is acting as a master.
192.168.200.101 data master
I need to delete indices older than 30 days with curator.
Here is my question.
Do I need to delete all 3 servers' or just a master's?
If it is only a master is there any es query to find who the master is?
Or if I need to delete all 3 servers' indices the master won't try to sync data what other 2 servers don't have depending on timing?
Thank you for your help in advance.
