Problem with recovery

alumoi · 05-03-2021, 03:10 AM

After a power surge I got a corrupted metadata.db.
Trying the recovery got me the following error:

Traceback (most recent call last):
File "calibre\db\restore.py", line 281, in replace_db
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'E:\\recovery\\metadata.db' -> 'E:\\recovery\\metadata_pre_restore.db'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "calibre\db\restore.py", line 129, in run
File "calibre\db\restore.py", line 285, in replace_db
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'E:\\recovery\\metadata.db'

OS is Windows 10. No other operations in progress on the library folder. Any ideas?

Try running the recovery using the command line calibredb tool

calibredb restore_database -r

Thank you, I will try and report it in a couple of weeks. I'm talking about 370K books here.
The gui recovery took only 10 ten days and failed

BTW: under linux it seems to work just fine, I tried it with only 1K books.

Working like a charm, thank you very much!
Now to some serious disk trashing
