  I'm skeptical that 5g is big enough. Without knowing much more
  about your setup (GPT v MBR; SWAP v No-SWAP; GELI v No-GELI),
  I'd just like to say that there are a couple combinations that would
  overflow that...
  
  E.g., GPT + GELI + SWAP by default would be better at 6GB per disk.
  E.g., MBR + SWAP would similarly work better at 6GB per disk.

I have not tried GELI or MBR in the new installer, but initially when I had
2gb virtual disks, the install could complete fine if I reduced the swap size.
I was just being stingy with virtual disk space since it was a test :)  Figured
2x4 = 8GB minus some room for swap ought to be enough.
  
  While there is code to make sure you don't use disks that are too small,
  I can't say whether it catches every edge-case.
  
  NB: The nature of the error doesn't look to be based on using disks that
  are too small; I just thought I would mention it because 5G looks too small
  to me for some layouts.

  If you send me the entire log, I can likely pinpoint the issue. That data
  displayed on Alt-F3 is saved in /tmp/bsdinstall_log

I have posted /tmp/bsdinstall_log at: http://p.bsd-unix.net/ps9qmfqc2

The corresponding procedure:

Virtualbox, created VM with 4 2.0TB virtual hard disks
Install
Continue with default keymap 
Hostname: test
Distribution Select: OK    
Partitioning: ZFS
Pool Type/Disks: stripe, select ada0-3 and hit OK
Install
Last Chance! YES

Thanks!
