You need to reindex your Jira.

Steps available here: https://confluence.atlassian.com/display/JIRAKB/Unable+to+Rebuild+JIRA+Index

Check first the drive for errors, though

Eric Sebian

I tried the steps listed in the above link but I'm getting the same problem when I try to re-index.

org.apache.lucene.index.CorruptIndexException: Unknown format version: -11

Task completed in 0 seconds with unexpected error.

... 22 more

And there are NO issues showing in JIRA at all. It also wont let me do a restore from a prior backup for the same reason.

Eric,

There's something really nasty on your disk. It can be permissions, for instance (you start jira as root, then as another user which has no perms to write to that dir). There can be a physical fault.

Edit: Saw that Nic just answered you, too. I fully agree with him.

Nic Brough -Adaptavist-

You won't see any issues until you've got a working index. Similarly for imports - the index needs to be usable.

The error you are seeing tells you that your index is completely broken. In some applications, this would be a serious issue, but in Jira, it's not painful because you can actually throw away the whole index and rebuild it from scratch, simply by clicking "re index"

However, you've got a serious error blocking that. As it's starting immediately, I'd say there's a critical problem with the index files - either you're out of space, the Jira user doesn't have read AND write AND delete permissions on the index directory, or you've got a damaged file system or disk. Simple fix -

Check the permissions on the index directory
Check the physical disk if possible
Stop Jira
Delete everything in the index directory from the operating system
Start Jira
Go re-index Jira

(If I were to lay a bet on this, I'd say it's going to be "not enough delete permissions")

Eric Sebian

still not working. And I changed the permissions:

[root@integration logs]# cd /opt/jira/releases/ProdJIRA/caches/indexes/
[root@integration indexes]# ls -lr
total 16
drwxrwxrwx 2 root root 4096 Aug 29 10:49 issues
drwxrwxrwx 2 root root 4096 Aug 29 10:49 entities
drwxrwxrwx 2 root root 4096 Aug 29 10:49 comments
drwxrwxrwx 2 root root 4096 Aug 29 10:49 changes

running out of options.

Radu Dumitriu

root# df -k ?

Radu Dumitriu

Sorry for the stupid question, but are you on the correct JiraHome ? Have you fsckd ?

Eric Sebian

there is plenty of space and there are no errors of the disk.
