Hello, I wanted to execute some S3 performance tests on my storage. If I am execute fio with the HTTP engine, I always receive the following output: fio: engine http not loadable fio: failed to load engine Bad option <http_verbose=0> Bad option <https=off> Did you mean loops? Bad option <http_mode=s3> Did you mean zonemode? Bad option <http_s3_key=someKey Bad option <http_s3_keyid=someKey> Bad option <http_host=http://…;. > Bad option <http_s3_region=eu-central-1> fio: job global dropped ” If I running the command “./configure”, I can see that the http engine is not available.
