This is my first e-mail, so, if this problem is already explained, i'm
sorry, couldn't find out where it is.
I'm out of ideas. This is my question:
I had an Elasticsearch up and running with 1 replica, 5 shards, 1 master
(data false) and 10 slaves, and every index configured by day (from
logstash). Since we changed to a hourly index, after 2 weeks and a needed a
maintenance reboot, Elasticsearch wasn't able to start properly. It started
assigning unassigned shards and a lot of timeouts came to happen.
After 5 days trying to recover, we decided to change the configuration of
our cluster to 1 master (data false), 10 salves and 1 shard 2 replicas
indexes, from scratch, without any old index.
My task now is to reindex those lost indexes. This is my problem:
I have 10 backup files (up to 400gb each) and i'm looking for ways to
reindex those indexes (little by little).
- Should i copy those indexes folder to the new cluster folder?
- I don't need to change to a daily shard, i just need Elasticsearch
to assign those indexes.
- Is there any way i'm able to differentiate replica folders from shards
folders?
We're using Elasticsearch 1.4.4 and each Elasticsearch is in an 8-core,
16gb ram dedicated machine.
