We are still using ElasticSearch 1.7 and have cluster with 6 data nodes.
One of the indices is allocated via Shard Allocation Filtering to 4 nodes in the cluster.
I'm trying to snapshot/restore it to another two nodes and don't have any luck.
- create backup with ignore_global_state: true
- create empty index with settings which allocate it to two nodes. close it.
- restore backup to closed index with ignore_global_state: true with assumption that it will respect index settings of closed index with mappings being the same.
