Not at all. A long thread is started where the user lost his pool, and
discussion shows it's a known problem. I love ZFS and I'm still very nervous
about the risk of loosing an entire pool.

Great to hear a few success stories! We have been experimentally
running ZFS on really crappy hardware and it has never lost a
pool. Running on VB with ZFS/iscsi raw disks we have yet to see
any errors at all. On sun4u with lsi sas/sata it is really rock
solid. And we've been going out of our way

It is possible that the stick you've tried has some

Hi,
Most of the time while waiting on a disk to fail is spent in disk drivers and
not ZFS itself. If you want to lower the timeouts than you can do so by
configuring different timeouts for sd. ssd or any other driver you are using.
