I was running Stardog on a Linux box when we lost power. On restart, the database appeared damaged, SPARQL queries now get errors like that below.
I tried to run repair on the database and was told:
$ ./stardog-admin db repair kb
Trying to repair qkb database, this might take a while depending on database size.
Database kb is invalid and the repair failed: Index cannot be repaired!
Nothing I can't re-create, but that's not very good behavior for a database.
