zfs discuss - Nov 2005 - mirror root drives

I have 2 internal disk drives, that I would like to mirror.  Can I do
that with zfs?  If so, how?

Thanks

If you intend to boot off the drives, no, you can''t
use zfs to mirror the entire disks.  We don''t support
booting off zfs file systems yet.

But if you want to mirror only part of the drives
(the part that doesn''t contain system software),
you can do so by first using format(1m) to define
a slice on each disk to be mirrored, and then
creating the pool like so:

zpool create tank mirror c0d0s6 c1d0s6

(assuming you''ve already used format to set up
slice 6 on each disk).

Any rough idea when installing the / root partition into a ZFS mirror pool would
be supported on either OpenSolaris or Solaris 10 production?

Thanks.
