We have one single node elastic cluster which was running fine till last week. From last week we saw frequently one index got corrupted and went in 'RED' state without any system crash and disk space problem.
When I see a particular index folder I found one corrupted_* file was present with following error
&failed engine (reason: [merge failed])Gchecksum failed (hardware problem?) : expected=8544add4 actual=77fd1c54©BufferedChecksumIndexInput(MMapIndexInput(path="C:\Program Files\Klera\elasticsearch\data\nodes\0\indices\pVdJlhg2SMSA9sjWUtROMA\0\index_38mus.cfs") [slice=_38mus.fdt])
Our team also diagnose hardware and found everything is fine.
Please suggest how to resolve this problem.
Thanks in advance.
