I've been using it for a good 5 years. OK, I had one time. When I removed a disk from a mirror, forced the remaining disk to operate writable as a single, then attempted to migrate it to single disk duplication, then shut it down before it finished migrating. That's not a sane way to handle data really, I was playing around with unimportant stuff. If it was real data, I would have mounted it read only, and copied it away.
