FTS is being used before the index is available, throwing errors (LMS9)

[LMSSonos]

Hi all

I upgraded toLyrion Music Server (v9.0.0, 1729751785) from 8.5.3 and I see these errors in the logfile. Is there a command to start migration so that the table will be created?

Thanks

Simplest might be to delete library.db while the container is shut down. LMS9 would trigger a full wipe & rescan anyway.

[LMSSonos]

Thanks, I deleted the ones in the /config/cache/library.* and restarted. The scan is still running but when I search i get

[24-10-25 06:21:54.0761] Slim::Schema::Storage::throw_exception (122) Error: DBI Exception: DBD::SQLite::db selectrow_array failed: no such table: fulltext [for Statement "SELECT count(1) FROM fulltext WHERE fulltext MATCH 'type:track mytrack*'"]

Are the tables only created once the scan is completely finished (takes probably 2 more days) or did I delete the wrong library.db

[michaelherger]

Yes, you can't search before the scan has finished. Creation of the full text index only happens at the end of the scanning process.

But that's actually a good pointer: I should catch this case. I've seen similar reports before, but never understood how that would happen. What you describe makes sense! Thanks for that heads up!

[LMSSonos]

Thanks! Just added more RAM to the container and restarting because else it took a few days to scan all

I assume this is because I aborted the initial scan - so will delete the /config/cache/library.* files and restart lyrion. right?

I relaunched a scan (without delete) to see if that helps

Edit: Scan completed, errors disappeart, all seems to work now. Thanks a lot!
