Hello,
I noticed strange issue with disk space consumption. I checked how much space my indexes take:
GET _cat/indices/*?v&s=store.size
Than I calculated total size (ofcoure store.size) it's about 1250 GB. Then I checked system information:
GET _cat/allocation?v
shards disk.indices disk.used disk.avail disk.total disk.percent
2030 1.5tb 1.6tb 272.1gb 1.9tb 86
2030 1.5tb 1.6tb 271.7gb 1.9tb 86
Also I cheked disk size with "du" command and get the same result 1.6 TB used per node.
This is dedicated drive for elasticsearch only. There is only elasticsearch information, I mean only /nodes directory.
So my qestion is - why Lucene indexes take 3 times more space than Elasticsearch indexes.
I hope I provided clear explanation of my issue.
