Loosing Books when renaming

[RudyBzh]

Hi,

I'm dealing with issues when I try to rename a book using Calibre.
If I change the Author or Title in Calibre (impacting the folder and file names), it often delete my book during the renaming process and I can find it anymore. It also happens using Download Metadata (because it changes Author/Title itself).

Here are 2 debug traces for exemple

And another one :

Hope it will be supported, I'm using a docker version of Calibre coming from lsio.

Any advice of what it could be and how I can solve this please ?

Thanks a lot.

Move your calibre library to a decent filesystem, like ext4 or similar and you will be fine.

Thanks for the reply.

Well, to be honest, I was running metadata.db on an SMB share with nobrl activated. Knowing it's something disliked by calibre, I move it on a local ext4 folder.
I did not move all my books located on the NAS (same host, but other VM), using the env variable CALIBRE_OVERRIDE_DATABASE_PATH.

Unfortunately, there's no change for me, I've just tried to do a change on a book using "download metadata", and on apply, I get the following error :

The thing I don't understand with the error is that it was a book without existing cover. Why does calibre complains about not finding such cover ?

Any help would be greatly appreciated please.
Thanks a lot.

There's is no solution other than using a properly working filesystem. calibre requires a filesystem that works correctly. Move your *full* calibre library to a proper filesystem and you will be fine.
