Hi! I have an app that uses ES 90.3, and i want to upgrade to 90.5. What's the fastest and more reliable way to do this? I haven't found anything about this particular situation. Have anybody done this before? Thank you -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

When we upgraded to 0.90.4 from 0.90.3 we did this: -1. Make sure you have curl installed on all Elasticsearch nodes. 0. Make sure you have enough capacity to handle queries with one less node. Two or three less nodes if you have a healthy sense of paranoia. 1. Make sure you have \> 2 nodes. 2. Make sure you have \> 0 replicas on each index. \> 1 replicas on each index if you have a healthy sense of paranoia. 3. Shut down one elasticsearch on one node. 4. Upgrade the code (deb package in our case). 5. Start elasticsearch. 6. Wait for the cluster state to go green again. Depending on the amount of data in your cluster this could take from seconds to hours. I ran this script so I could see updates every second: until curl -s localhost:9200/\_cluster/health?pretty | tee /tmp/status | grep "status" | grep "green" do cat /tmp/status echo echo "Still waiting..." sleep 1 done 1. Repeat 3-6 on each node. If you did it right no one will notice but your network monitoring tools. They'll see a furious spike in data transfers. You can prevent this spike and speed up the process by turning off shard reallocation before step 3 and turning it back on after step 5 like this: 2.5. curl -XPUT localhost:9200/\_cluster/settings?pretty -d '{ "transient" : { "cluster.routing.allocation.disable\_allocation" : "true" } }' 5.5. curl -XPUT localhost:9200/\_cluster/settings?pretty -d '{ "transient" : { "cluster.routing.allocation.disable\_allocation" : "false" } }' This setting affects your whole cluster so make sure you don't accidentally leave it off.

In addition to upgrade steps, I'd also recommend to back up data in case there is any issue with newer version and you may need to downgrade back to older version. The index data after upgrade may no longer be compatible with old version. On Friday, October 25, 2013 8:58:56 AM UTC-4, Adrián Van Langenhove wrote: > Hi!

We currently have just 1 node. We can stop the service for a couple of hours, and we don't need back up of info, we can generate it again. Is there any basic script to upgrade?

If you can afford to stop the node, then just copying the data folder over into the new installation should do the job.

Can you disable indexing? If so, after disabling indexing and disabling allocation (per Nik's excellent suggestions), you should flush your indices so that the transaction log is (hopefully) clear for when you re-enable allocation. Just saw that you have only one node. Even if you have only one node and allocation does not pertain to your situation, flushing is still a good idea. Other things to look at for is sub-directories. By default, the data/plugin/log directories are in the elasticsearch directory. You can copy these directories to your new install directory, but hopefully you have already configured them to live outside of elasticsearch. If you have not, then use this upgrade time to enable this best practice. Some plugins might not work between versions, but the most common ones do.
