Lucene index corruption

[chris chadwick]

I am on V6.4.12 and getting error:

Lucene search terminated abnormally: com.atlassian.jira.issue.index.SearchUnavailableException: com.atlassian.jira.util.RuntimeIOException: org.apache.lucene.index.CorruptIndexException: document count mismatch: deleted docs count 0 vs segment doc count 242 segment=_zx8c

Is there anything I can do to fix.

We need to get this working prior to moving to the Cloud.

Hi @chris chadwick 

Indexes can get broken or corrupted. Direct database updates are notorious for causing these issues.

Most can be fixed by re-indexing

Go to the indexing page and start a complete index re-build, not the background index. Jira  will be unaccessible for a short period depending on your instance size.

(Short cut - type 'gg' and then enter 'indexing' in the pop up menu search dialog)

Thanks with your help with this it is much appreciated.  The index re-build took much longer than expected but has resolved the issue.
