If you care to keep your pool up and alive as much as possible, then
mirroring across SAN devices is recommended.
One suggestion I heard was to get a LUN that's twice the size, and set
"copies=2". This way you have some redundancy for incorrect checksums.
This only helps for block-level corruption. It does not help much at
all if a whole LUN goes away. It seems best for single disk rpools.
