I tried to create a basic setup with one Elasticsearch pod.
The jvm_memorry for this pod is 8GB.
I didn't notice the pod for some time and today I found that the above-mentioned error. it says that all my shards are failed.
I checked the data size and it grows to 37GB.
Now the entire setup is down and I don't want to lose this data.
The solution I think at this moment is to remove the backend volume and attach a new one and start the elastic pod. once everything is in place then somehow reindex the old data with new volume.
I don't know how to do it and if it is really a viable solution.
I am quite new to Elastic search and looking for help here.
