When your nails database is corrupted or there is an issue shrinking the database, use the following steps to create a new nailsd.db database:

1. Open a command-line session on your server.
    
2. Stop the nails service using the following command:
   
   service nails stop
    
3. Copy the old database to a temporary location using the following command:
   
   cp /var/opt/NAI/LinuxShield/etc/nailsd.db /tmp/nailsd.db
    
4. Remove the database using the following command:
   
   rm /var/opt/NAI/LinuxShield/etc/nailsd.db
    
5. Create the new database using the following command:
   
   sh /opt/NAI/LinuxShield/bin/mknailsdb /var/opt/NAI/LinuxShield/etc/nailsd.db
    
6. Start the nails service using the following command:
   
   service nails start
