zpool can't bring online disk2

Since it's a HAST device, you have to initialise the disk via hastctl. Once
that is done, the /dev/hast/disk2 GEOM device node will be created.
Then you can 'zpool replace' it.
One step at a time. :) And you've skipped a few.
1. 'zpool offline' the defective disk
2. Physically remove the defective disk
3. Physically insert the new disk
4. Initialise it as a HAST resource via 'hastctl'
5. 'zpool replace' it using the /dev/hast node
6. Wait for the pool (and HAST) to resilver it
7. Carry on as per normal
