Hi All,I'm using Fuseki 3.9.0. I have a TDB-backed graph. Configuration file is
attached.Everything works, including inference on triples added
incrementally.I'd like to reset the TDB content.
The SPARQL directive "DELETE { ?s ?p ?o } WHERE { ?s ?p ?o }" is too slow.
The directive "CLEAR ALL", once I've put something in the TDB, gives the
following error:

[6259] 500 Read-only block manager (5 ms)
If I try to delete the dataset by using the "remove" button on web interface I
get:
Sorry, removing dataset /pluto did not work, because: 'There are 6262
configuration files, not one. Delete not performed; clearup of the filesystem
needed.'
Anyway, I'd like to have "CLEAR ALL" command working: any idea?
Thanks
