Options:
- Try to repair.
- Restore from backup.
- Delete it & start over.
To repair, you’ll need to SSH into your Synology (FAQ 14). See Repair A Corrupt Database, Linux section, for the instructions you’ll have to issue. My DS918+ has sqlite3 installed, so you may not have to install it on your system (the article says it is not installed on Linux systems).
See Synology FAQ 17 to restore from a backup.
Deleting the database is almost like starting over. You files are safe, but you’ll have to re-create libraries, re-share them if you share with others, etc. See the Repair A Corrupt Database article. Look for the text in the blue box, about the fifth paragraph.
