I'm running Windows 11 as the host system. I run Oracle Virtualbox with various Linux distros installed as Virtual Machines. In general this works great - with shared folders I can access any drive on the host system that I choose to share as a "shared folder".

So from Linux Mint, Debian, Fedora ... I can create, read, write, modify ... files in the Windows environment. E.g. with LibreOffice I create a document in Win 11 stored on a disk drive that is shared as a folder with one of the Linux VMs. From this virtual machine I can read, write etc. those files with LibreOffice running under Linux or any other Linux software that can understand that format.

Now, specifically in Win 11 Calibre I can save some books to a directory on a shared folder. Then in a Linux Calibre I can use Add Books to read them and add them to my Linux Calibre library (and vice versa of course.)

What I can't do is open or create a calibre catalog on the shared folder.

This is the traceback I get trying to open a library:

calibre, version 8.4.0
Corrupted database: The library database at /e/calibre-libs/test appears to be corrupted. Do you want calibre to try and rebuild it automatically? The rebuild may not be completely successful.

Traceback (most recent call last):

apsw.IOError: IOError: disk I/O error

Should Calibre be able to do this?

Any info would be great. Thanks,
