Hi @Dali,

Looks like the option to run a background re-index is not available to you due to the corruption.

However, you can still run a "Lock JIRA and re-build index". Although this will mean that your instance will be inaccessible to users until it completes.

As a side note, I would recommend ensuring a back-up of the indexes is scheduled. This can be done on the indexing page. Being able to restore to one of these will help if the re-index doesn't solve your corruption.

Regards,

Gary

Thank You @Gary Pasquale and All the rest For your help, I really appreciate it ! 
I managed to get all of my tickets back by running the "Lock Jira and rebuild Index" .

I recommend following the steps in this KB:  https://confluence.atlassian.com/jirakb/unable-to-rebuild-jira-application-indexes-228623566.html

Since you're already seeing this error that you cannot do a background index, it is possible that you might have to stop Jira and remove the existing indexes you have.  This way you can have Jira create a clean index set after starting it again.

Hi @Dali

Do a full reindex of the jira instance..

Refer to https://confluence.atlassian.com/adminjiraserver071/search-indexing-802593000.html on reindexing

Hi @Dali

As Gary and Andrew pointed out, do a lock JIRA and rebuild index.

There will be downtime depending on the size of your JIRA instance. But that will fix this problem. Well, not seeing tickets is already a downtime isn't it..

@Fazila Ashraf Yes, it's definitely a downtime for us. Fortunately  locking Jira and rebuilding indexes did the trick, Again thanks to all of you for helping
