The cause may vary but a few known causes are:
- Re-indexing following the addition of a 'custom field' when a user is using GreenHopper.
- If two issues are somehow linked with each other using an issuelinktype which doesn't exist anymore.
- When an Epic link source is not an Epic, although this is less common.
ソリューション
データベースの変更を行う場合は 必ず事前にバックアップを取得してください。可能な場合はテスト サーバーで変更を試すことをおすすめします。
1. Run the integrity checker: Using the Database Integrity Checker
2. Try to Re-index Jira again.
3. If re-indexing (also startup reindex or catch-up) still fails, then continue on with the next steps.
Please run the following queries on the Jira DB:
3.1 To check if an issue source doesn't exist anymore:
SELECT * FROM issuelink WHERE SOURCE NOT IN (SELECT ID FROM jiraissue);3.2 To check if an issue type doesn't exist anymore:
SELECT * FROM issuelink WHERE linktype NOT IN (SELECT id FROM issuelinktype);3.3 To check if an Epic link source is not an Epic:
SELECT *
FROM issuelink l
JOIN issuelinktype ilt on ilt.id=l.linktype
JOIN jiraissue i on l.source=i.id
JOIN issuetype it on it.id=i.issuetype
WHERE ilt.linkname='Epic-Story Link'
AND it.pname<>'Epic'4. If any of the previous queries returns a result, then:
- Jira をシャットダウンします。
- Execute the following query on the DB
- If the first query (3.1) returns results:
DELETE FROM issuelink WHERE SOURCE NOT IN (SELECT ID FROM jiraissue);- If the second query (3.2) returns results:
DELETE FROM issuelink WHERE linktype NOT IN (SELECT id FROM issuelinktype);- If the third query (3.3) returns results
DELETE FROM issuelink WHERE id in (
SELECT l.id
FROM issuelink l
JOIN issuelinktype ilt on ilt.id=l.linktype
JOIN jiraissue i on l.source=i.id
JOIN issuetype it on it.id=i.issuetype
WHERE ilt.linkname='Epic-Story Link'
AND it.pname<>'Epic' )- Jira を再起動します。
- Manually perform a re-indexing
5. If re-indexing still fails, then:
- Run the command
select * from jiraissue where issuetype is null;- If this returns any rows, then please find an appropriate issuetype for the issue key returned in the previous query. For this we run:
select * from issuetype;- Once the id of the issue type if identified, run the below sql:
update jiraissue set issuetype = <<id found from the above query>> where id = <<jira issue id found in the first query>>
