BTW while reading mount manual:
async All I/O to the file system should be done asyn-
chronously. In the event of a crash, it is
impossible for the system to verify the integrity
data on a file system mounted with this option.
should only use this option if you have an
tion-specific data recovery mechanism, or are
to recreate the file system from scratch.
shouldn't we add: "it is as dangerous as linux in normal operation mode"
