Looking for help with restricting shard auto failover. If we have 1000 indexes and some times it requires nodes to be restarted. In the event of node restarts shards are automatically failed over or getting rebuilt on different nodes. This is causing lot of time to build and recover. Instead, is there a way disable shard failover and restart the node will bring it back shards online immediately. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

If the node restart is planned, you can temporarily disable shard allocation with: cluster.routing.allocation.disable\_allocation or cluster.routing.allocation.disable\_replica\_allocation Check out the cluster shard allocation page[http://www.elasticsearch.org/guide/reference/modules/cluster.html](http://www.elasticsearch.org/guide/reference/modules/cluster.html)for more details. Note that replicas will still be promoted to primaries if a primary goes down, and ES will still sync various changes when the node comes back up. -Zach On Tuesday, February 19, 2013 1:41:22 AM UTC-5, Krishna Reddy wrote: > Looking for help with restricting shard auto failover.
