Thank you!

I emphatically agree, unencrypted ZFS on top of GELI or LUKS encrypted block devices is the way to go for now. Plus it also has the benefit of not leaking metadata like a sieve.

My mistake was placing too much trust in ZFS's reputation for data integrity; clearly not all features hold that value in the same regard.

The openness of OpenZFS was a real saving grace. If this had occurred on a propriety SAN, that data would be gone forever.
