but does anyone know of any way of fixing this corruption short of
destroying the pool, creating a new one, and restoring from backup? Is
there some way of exporting and re-importing the pool that has the
side-effect of doing some kind of fsck-like repairing of subtle corruption
I'd be looking at the hardware or drivers.
What disk model are you using and what controller?
Are you using port multipliers and are there known issues with your hardware
