Hello guys !
I'm faced with this error while indexing:
[2020-10-24T18:18:31,520][WARN ][o.e.i.e.Engine ] [mini-server] [release] failed engine [lucene commit failed] org.apache.lucene.index.CorruptIndexException: checksum failed (hardware problem?) : expected=d464d53f actual=a462587c (resource=BufferedChecksumIndexInput(MMapIndexInput(path="/var/lib/elasticsearch/nodes/0/indices/ZyUEzVTkS1S7geQrMnwI7g/0/index/_18_Lucene84_0.doc")))
[2020-10-24T18:18:31,622][INFO ][o.e.c.r.a.AllocationService] [mini-server] Cluster health status changed from [GREEN] to [RED] (reason: [shards failed [[release]]]).
Then my index is flagged as RED and the cluster/node is not reachable anymore.
I thought it was an hardware problem as indicated then I changed my only local hard drive to a brand new one fast Kingston.
but I have exactly the same problem.
I have only 1 computer, then 1 cluster, 1 node.
16Gb of Ram
I pushed the heap size from 1Gb to 6Gb: same problem.
I tried to index from bulks of 1000 documents to 1 documents (1 by 1): same problem.
I run with:
- the latest Elasticsearch version: 7.9.3
- I'm very large on HDD free space.
- I pretty sure that did not happened on ES version 6.x
I don't know where to investigate anymore...
I will be thankful for any help.
