Hi Jeff Robert,
Thanks for the reply. Your interpretation is correct and the answer spot on.
This is going to be at a VIP clients QA/production environment and first

It should not. As long as all the disks are visible and ZFS can read
the labels, it should be able to import
Most ZFS improvements should be available through patches. Some may require
moving to a future update (for instance, ZFS booting, which may have other
implications throughout the system).
On most systems, you won’t see a lot of difference between hardware or software
mirroring.

It would be really great to automatically select the proper recordsize
for each file! How do you suggest doing so?

One technique would be to keep a histogram of read write sizes.
Presumably one would want to do this only during a “tuning phase” after the
file was first created, or when access patterns change. (A shift to smaller
record sizes can be detected by a large proportion of write operations which

I don't understand why you can't use 'zpool status'? That will show
the pools and the physical devices in each and is also a pretty basic
command. Examples are given in the sysadmin docs and manpages for
