Library Damaged - Need Repair

[windom]

Last night I started copying books from one library on my laptop to another on my server. This is a regular thing for me. However, some time later, I close my laptop for the night. I opened it up a couple of minutes later because it didn't suspend. When I opened it, I found Calibre in the middle of the process that I forgot. I waited for it to resume but it never did. There was no response from Calibre when I tried to shutdown so I just killed the processes and shutdown my laptop for the night. The next morning I thought I'd just start the copy over again. When I tried, the copy process did nothing. The copy window hung at 0%. I killed and started a few times with the same result. Finally I tried to open the destination Library but it would not open. I figure it must be damaged. What can I do? I am running 7.49 on Ubuntu. When I shut the laptop the first time it definitely stop the network. Also, I was doing copy with delete not just plain copy.

Next to the Library Icon, there is a little arrow. Maintenance options are there.
you can try the repair., the last item tries to rebuild from the OPF stored with each book (plan on some time being consumed).

How do I do this if I can't open the Library?

Will Calibre open at all? This is a metadata.db reconstruction tool, that looks in each folder (where you normally don't need to look) and reads the .opf file and rebuilds the database from that.
You can also do this with the command line tools (syntax in the on-line manual)

I finally fixed the library. But it wasn't a direct route. I issued the command calibredb restore_database -r --with-library=/media/Calibre/Fiction/. It resides on an NFS share. Looked liked it work. No joy. Still could not open the library. Restarted the server, NFS, etc. Still no joy. Finally took the server down and moved the USB drive to my desk where I copied the library directory to my local drive. I reissued the command (changing the path of course) and then there was joy. Copied it back to the USB drive and there was still joy. Moved the drive back to the server and it still worked. I mention all this so others don't give up easily. Rescue still may be possible. Why it didn't work on the server is now a quickly fading issue now that the library is fixed.

Thanks for the tip on using the command line.

Caching can be your enemy with desktop (single user) databases)
If you have fine control, disable the caching for the Library folder path. You will take a performance hit, but your data will be safer
