Hi,

Any plans or perhaps an implementation is already underway for O_DIRECT (direct I/O) support? When attempting to use this feature with 'fio' we of course get a failure:
fio: looks like your file system does not support direct=1/buffered=0
fio: destination does not support O_DIRECT

Thanks,

Marc

@msmith626, Can you please share your fio execution command with full parameters + your output of rapiddisk --list.

@pkoutoupis Please disregard, I was specifying /dev/rc-wt_sdb instead of /dev/mapper/rc-wt_sdb so that was my bad! Closing...
