We have an environment with 3 IDX in cluster. One of them (splunk_idx1) fall and when it recovers, messages like this appear in the searches:
[splunk_idx2] Failed to read size=736 event(s) from rawdata in bucket='db_index_13_5F5D7B9C-8A97-43A6-8DEB-0CFB1D29347B' path='/opt/splunk/var/lib/splunk/db_index/db/rb_1603347108_1603313418_13_5F5D7B9C-8A97-43A6-8DEB-0CFB1D29347B. Rawdata may be corrupt, see search.log. Results may be incomplete!
We have run the splunk fsck scan command, but no corrupt buckets appear on the results. But when we try to repair the bucket with the splunk rebuild comand, the following message shows:
failed: Error reading rawdata: Error reading compressed journal while streaming: gzip data truncated, provider=/opt/splunk/var/lib/splunk/db_index/db/rb_1603347108_1603313418_13_5F5D7B9C-8A97-43A6-8DEB-0CFB1D29347B/rawdata/journal.gz Rebuilding bucket failed
Which could be a possible solution for this issue?
