Hi, I have a cluster in ec2 and I want to make cluster wide consistent backup by: 1)set index.translog.disable\_flush=true 2)make manual flush 3)snapshot elastic search datadir EBS volume on each node. The question the index.translog.disable\_flush and [http://localhost:9200/\_flush](http://localhost:9200/_flush) are per node actions which i need to run on each node or they are cluster wide and can be issued just once against any node in the cluster? Thanks Alex ---

Flush and update settings are per-index operations. If you will run them without specifying index name (using /\_flush and /\_settings) on any node in the cluster, they will run on all indices on all nodes.

Thanks for your reply Igor And is there way to know if the /\_flush has finished on all cluster nodes?

The REST \_flush method is blocking. It returns when \_flush on all shards either finishes successfully or fails and returns corresponding numbers.
