mirror. that's all.

Which doesn't really address the issue of what happens if a drive that is
part of a big ZFS is removed (because it's broken).

it will say "read error" on all files and directories that happened to be placed on that disk!

Just to be clear, ZFS pools contain one or more VDEVs (Virtual devices). Each VDEV consists of one or more physical partitions and can be configured as a mirror, stripe, stripe with one parity, or stripe with 2 parity. ZFS does striping with no parity across all VDEVs in the pool. Thus with ZFS, if you lose a VDEV, you lose the whole pool.

Hopefully that clears things up a bit.
