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.
How does one do that? Is it as simple as using "attach" instead of
"add" when creating the new vdev?
For example:
zpool create mypool raidz2 disk0 disk1 disk2 disk3 disk4 disk5 disk6
zpool attach mypool raidz2 disk7 disk8 disk9 disk10 disk11 disk12 disk13
Would it work for adding a third raidz2 vdev?
There is no support in ZFS for nested vdevs like this.
