Hi,

My current setup has 1 dedicated master node and 2 master+data nodes to avoid the split brain problem. I have to archive the indices every 2 months and have common SAN for the 2 data nodes. I have gone through the Curator documentation and need your inputs. I'm not sure how SAN works -

1. Can I mount the same SAN directory on both the data nodes?
2. Can I create a repository on SAN using Curator?
3. Do I have to snapshot indices from both the data nodes or just one as one data node contains all the data

Thanks in advance!

You _must_ mount the SAN directory on _all_ data _and_ master nodes in exactly the same path.

There is a hidden, command-line script called `es_repo_mgr` that gets installed alongside Curator at install time. It can help with that. The command-line has extensive help dialogues to help with that process. Feel free to ask for more assistance here.

Snapshots are always cluster-wide. While Curator will only need to connect to a single node in the cluster, the Elasticsearch Snapshot API is always cluster-wide. It is not possible to snapshot just the indices from a given node.
