If you lose 1 vdev, you lose the pool.
As long as 1 vdev is striped and not mirrored, that's true.
You can only afford to lose a vdev, if your vdev itself is mirrored.
You could, for example, create 2 vdev's of raidz2, and instead of striping
them together, mirror them. Then you could lose one of the raidz2's, and
the other half of the mirror is still up.
Can you layer vdevs hierarchically? Last time I looked, you couldn't
do that.
You mean like a mirror of raidz or a raidz or mirrors ?
No the admin interface doesn't allow you to do that.
