Found my Fulcrum server was down today and reporting this error. Restarting the service brings the same error. Any idea what the issue may be?

Usually caused by unclean shutdown, duplicate of #41. You will have to start over with sync. It is a good idea to take backups of your Fulcrum data directory to restore from if this happens.

FYI, it helped me to keep my DB on a filesystem that can do CoW reflinks like btrfs, that way you can just cp --reflink=all the data directory anytime to quickly take a backup.
