This is a bad idea.

If you want repair, you need to either set more than one copy in ZFS (still pretty dumb) or use multiple drives in a raidz (or mirror, though raidz is more efficient).

When you try to partition a drive like this (or configure ZFS to write multiple copies) you loose everything in the event that the whole drive fails. Honestly, it's a far better plan to just use multiple drives in a raidz so that whole-drive failures can be reconstructed in addition to data corruption.

Please read the thread before commenting. The scenarios we're discussing are explicitly in the context of single storage device systems getting helped by the new healing replication feature. Huge numbers of systems do not have multiple drives nor even necessarily the ability to have multiple drives. Nobody is suggesting it's optimal. I've run ZFS for 12+ years now with hundreds of systems. You don't need to tell us the obvious.
