I know nothing about ZFS, so sorry if these are dumb questions. Can you have an array that contains a single disk? And if you can, then * Can you add as many

I know nothing about ZFS, so sorry if these are dumb questions. Can you have an array that contains a single disk? And if you can, then * Can you add as many single drive arrays to a pool as you like? * Can you migrate data off of a given single-drive array on to other single-drive arrays in the pool and then permanently remove the array from the pool?

Yes, yes, no. Plus a single disk array has no redundancy.

  Minor nit: depending on your definition of redundancy, you may set copies=n, on a single vdev pool. You won't get hardware redundancy but will get data redundancy.
