Ben,
never trust a benchmark, you haven't faked yourself!
There are many benchmarks out there, but the question is, how relevant are
they for your usage pattern. How important are single stream benchmarks, when
you are opening and closing 1000s of files per second or if you run a DB on

Hi Justin,
Maybe I misunderstand your question...
When you export a pool, it becomes available for import by using
the zpool import command. For example:
1. Export tank:
# zpool export tank
2. What pools are available for import:
# zpool import
pool: tank

It still has the issue that the end user has to know where the root of
the filesystem is in the tree (assuming it's even accessible on the
system -- might not be for an NFS mount).

As others mentioned, doing raidz with two slices on the same disk is
