I read about ZFS on wikipedia, this looks very good.

I would like to try and help with testing.  I have a box with six
drive bays and a bunch of SCSI drives at my disposal in my
office.

Anything in particular you would like tested?

I assume steps are something like:

    - install -CURRENT with debug kernel

    - (maybe??) pull code from your perforce branch

    - define slices as geom providers

    - put RAID-Z on top

    - try to break it:

        * run postmark from a number of consoles

        * remove drive, make sure array functions, then put back in
          and make sure array rebuilds properly

        * generate scsi disk errors somehow?

        * add a disk to increase capacity (if ZFS supports this)

I've not yet run -CURRENT so this is new territory for me.  Any
general guidelines would be welcome.

Also, is this the right list for this?
