I noticed yesterday that for the past few days new content was not being picked up by Plex. I did the [Plex dance](https://forums.plex.tv/t/the-plex-dance/197064). I did just about everything. Then I stumbled upon @ChuckPa github about the DBRepair script to correct the issue. Well just my luck it failed with this error code Runtime error near line 3528125: UNIQUE constraint failed: fts4\_metadata\_titles\_icu\_docsize.docid (19) Error 1 from Plex SQLite while importing from ‘./dbtmp/library.plexapp.sql-2024-09-13\_18.17.12’ Also after trying to manually trying #6(reindex) I get this error code: Backing up of databases Backup current databases with ‘-BACKUP-2024-09-13\_18.49.20’ timestamp. Reindexing main database Error: stepping, database disk image is malformed (11) Reindexing main database failed. Error code 11 from Plex SQLite Reindexing blobs database Reindexing blobs database successful. Reindex complete. Not sure what to do at this point. For a little back story, I was running my Plex server on my Synology via the Plex package from the package center. I built a new Unraid server, and migrated everything into the new Docker container. I did have trouble when zipping the database on the Synology, certain files would fail to zip, but none the less I migrated everything over and spun up the container on Unraid ([linuxserver.io](http://linuxserver.io)). Plex has been working fine for months on the new server up until yesterday. Someone please help me lol ---

This is a serious error. At any time, was your PMS run from network storage ? The database has significant damage and is not salvageable Use my tool to select and make active one of your backup databases. (Restore using a backup DB) Use the --sqlite and --databases options to help you as it will have a lot of work to do Even SQLite cannot do anything with the DB [https://www.sqlite.org/rescode.html#corrupt](https://www.sqlite.org/rescode.html#corrupt) ---

Plex runs locally, I do however have content on my synology. The synology shares are mounted in unraid via SMB. ---

It worked. Thank you so much for the help. It searched for the latest useable backup which was apparently about 2 months ago lol. After it got replaced I ran the automatic tool again to ensure it all checked out. Im back up and running just rescanning libraries and refreshing metadata now. Thank you so much for this tool @ChuckPa ---

@Unibrowser Excellent! That’s how it should work… 🙂 At this point, I do suggest: 1. Let scanning and metadata finish catching up 2. When all idle, Run the tool again to “auto” cleanup & optimize 3. Stop Plex 4. Make a full, proper, backup (tar works) of all of Plex’s data ---
