On the other hand, I've had two NetBSD machines running with all
filesystems in async mode for several months, now. One of these
machines is getting beat since I'm running lots of benchmarks on it.
The X benchmarks, in particular, seem to kill it quite regularly (must
be bugs in the 3.1.2E beta server), forcing me to hit reset since X
gets totally hung, and it's not networked to anything.
I have yet to lose a single file, that I know of, running my drives in
async mode. In fact, when it comes back up, I look to see how much of
the data it finished collecting in the benchmark file it was writing
before I reset it. The file is always there.
Of course, your results may vary...
