I have one master 1 data and 1 search node,Then are running on AWS During indexing ,cluster status became from green to red,and there is part of unassigned shards,I terminated the only data node by mistake,and start a new VM and let it join into cluster,It turns out status is still red and All of shards is unassigned. 1.is there any way to recover the status to green? 2.is there any chance I can recovered the data node's data?because I terminated the only data node 3.And if I met this situation again,I mean "During indexing ,cluster status became from green to red,and there is part of unassigned shards".How can I recover status to green -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Had a similar issue. I managed to recover all my unassigned shards and get the cluster back to a green status using the following procedure. It could probably be streamlined but it works. 1. Dump list of unassigned shards to text file. Using the following command curl -XGET [http://localhost:9200/\_cluster/state?pretty=true](http://localhost:9200/_cluster/state?pretty=true) \>\> /tmp/unassign.txt 1. VI unassign.txt 2. Search the file for UNASSIGNED 3. Running the following command on each unassigned shard curl XPOST -s '[http://localhost:9200/\_cluster/reroute?pretty=true](http://localhost:9200/_cluster/reroute?pretty=true)' -d '{ "commands" : [ { "allocate" : { ``` "index" : "*INDEX TO WISH TO REASSIGN*", "shard" : 0 , "node" ``` : "_NODE YOU WISH TO ASSIGN IT TO_", "allow\_primary" : 1 } ``` } ] ``` }’ If the shard is a number other than 0 change it to reflex that as well.

I would set back and ask the question: why are you using a single data node and a single search node? Are you servers vastly different? Dedicated search nodes have the primary function of offloading the result aggregation process from the data nodes. However, you only have one data node, so the search node is aggregating the results from a single server. -- Ivan On Mon, Dec 16, 2013 at 2:48 AM, xiaoliang tian [xiaoliang.tian@gmail.com](mailto:xiaoliang.tian@gmail.com)wrote: > I have one master 1 data and 1 search node,Then are running on AWS > > During indexing ,cluster status became from green to red,and there is part > of unassigned shards,I terminated the only data node by mistake,and start a > new VM and let it join into cluster,It turns out status is still red and > All of shards is unassigned. > > 1.is there any way to recover the status to green? > 2.is there any chance I can recovered the data node's data?because I > terminated the only data node > 3.And if I met this situation again,I mean "During indexing ,cluster > status became from green to red,and there is part of unassigned shards".How > can I recover status to green > > -- > You received this message because you are subscribed to the Google Groups > "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com). > To view this discussion on the web visit > [https://groups.google.com/d/msgid/elasticsearch/bc9de699-59f6-46a9-8384-64a76878b03d%40googlegroups.com](https://groups.google.com/d/msgid/elasticsearch/bc9de699-59f6-46a9-8384-64a76878b03d%40googlegroups.com) > . > For more options, visit [https://groups.google.com/groups/opt\_out](https://groups.google.com/groups/opt_out). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
