When the filesystem that Splunk uses to store its indexes becomes unavailable, goes into read-only mode or Splunk crashes, inconsistencies are sometimes introduced in the metadata files of some indexes and buckets. tsidx stands for time-series index file. When the files are subsequently downloaded to indexers, SmartStore will automatically decompress the files before placing them in the cache. The data is reindex again. The results are written locally to the instance you run the search on so they are not replicated across an index cluster. Hi everyone. Or you can make the below changes in Indexes. data, Hosts. tsidx files on the indexer, parallel to the buckets that contain the events referenced in the file and which cover the range of time that the summary spans.
