ElasticSearch went stopped automaticaaly and shards are went to UNASSIGNED due to this disk failures.
Continously we are facing this issue and elasticsearch stopped automatically,When we are facing the issues ,we need to loss the all shards data's in that particular box.
Per day we have writing 4 Billion documents of 2 TB (approx).
My question was
1)Elasticsearch heavy indexing is the reason for disk failure?
2)A single Bad sector in a Disk(12 hard disk per box) will lead a data loss in all disks (Entire Box)
I have another one regarding the second one. We have not enabled replica,in this scenario. In a single box we have stored the data(with 12 hard disks).we have a failured in any one of the disk ,it would lead the failure in total shards as well entire box.Is there any way to override from this.
Can you please explain ,How the OS handles these things.Thanks in Advance.
