Log:
  8969 Cannot boot from RAIDZ with parity > 1
  
  illumos/illumos-gate at 0fb055e81fd0cda5221da8ddd98b2f8d1fc6bdbe
  
  At present it is possible to boot from a root pool that is on RAIDZ but not
  one that is on RAIDZ2 or RAIDZ3.  This is because, at the time the pool
  version is checked to ensure support for dual/triple parity, the uberblock
  has not yet been loaded into the SPA and therefore the code determines that
  the pool version is too old and returns ENOTSUP.
