Restoring Database Process Hanging?

skfed · Yesterday, 09:33 AM

My library was working just fine until I tried to delete a book, then it gave me an I/O error. I closed calibre to see if that would solve it. However, upon attempting to reopen calibre, it gave me a message that my database was corrupted and needed to be restored.

I selected the restore database option, and it's been restoring the database for about 16 hours. For 12 of those hours, it's been on the same screen where there's no progress percentage, it just lists the last book that I added before the original issue. Is there something else I should try? Is this just a wait and see time? How long should I wait before deciding that this isn't going to work? Any other suggestions?

Given that you had an I/O error, could it be that your drive is corrupted?

I don't think so because I haven't had any issues with anything else on that partition, but is there a way to check? I'm on a mac running Sequoia.

I/O errors typically indicate imminent disk failure. You can also try restoring the database from the command line, you might get more insformation that way

In Terminal.app run

/Applications/calibre.app/Contents/MacOS/calibredb restore_database -r

Thanks for that - it's my main drive so ooof, but at least I have a heads up!

The thing to do is make a full backup in case the drive is on the way out.
