I'm maintaining a small cluster of 9 nodes, and was trying to perform rolling restart as outlined here: [http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/\_rolling\_restarts.html#\_rolling\_restarts](http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_rolling_restarts.html#_rolling_restarts) The problem is that after I disable reallocation and restart a single node, it appears it looses all its shards indefinitely (until I turn back reallocation). So if I do this for all nodes in the cluster I'll run out of primary shards at some point. I have an upstart task for Elasticsearch, so I stopped nodes with that (it sends SIGTERM). I tried the shutdown API but it did have the same effect -- after node joins the cluster, it doesn't own any shards, and that doesn't change if I wait for a while. Am I doing something wrong? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

You have to reenable allocation after the node comes back and wait for the shards to initialize there.

So this means the tutorial is wrong (current version): 1. Disable allocation 2. stop node 3. ... 4. start node 5. Repeat 3-5 for the rest of your nodes 6. Re-enable shard allocation using ... It should be: 1. disable allocation 2. stop node 3. ... 4. start node 5. enable allocation 6. repeat steps 2-6 for the rest of your nodes -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
