Hi Markus,
Jeff Bonwick integrated this feature so I'll let him describe it.
In a nutshell:
If you create a RAIDZ pool in OS 11 Express or if you are running at
least build 129, some of the pool metadata is mirrored automatically.
This is a performance feature that should increase read I/O performance,
by decreasing IOPS. This feature should improve directory searches,
for example.
Some mirrored metadata in a RAIDZ pool in b129 is done automatically,
but it doesn't provide any additional redundancy. Redundancy is still
determined by your RAIDZ configuration (raidz1, raidz2, or raidz3).
This is a performance enhancement only.
No property exists to disable or enable it.
Its automatic, for your data lookups...

It should be in Solaris 11 Express, has anyone tried this? How this is
supposed to work? Any documentation available?
