I've recently encountered and error. Caused by: org.apache.lucene.index.CorruptIndexException: Unknown format version: -11

Eric Sebian

but when I follow the suggested fix:

Here are the following steps on how to fix this problem:

1. Stop JIRA.
2. Remove all the contents from under the JIRA index directory.
3. Restart JIRA.
4. Perform a full re-index via Administration >> System >> Indexing.

the re-indexing fails.

the re-indexing information box at the top states that I have recently made a change to a custom field, but I dont know what change I've made. Please advise.

What error do you have when you try to reindex ?

BTW You do not need to remove ALL directories.

These directories must exist and must have correct perms (rwx for the user running Jira).

• • <JIRA-Home>/caches/indexes/changes
  • <JIRA-Home>/caches/indexes/comments
  • <JIRA-Home>/caches/indexes/entities
  • <JIRA-Home>/caches/indexes/issues
