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
ZFS on the opensolaris ZFS community page.
I realize it's not quite the same command as in UFS, and it's easier
when things remain the same, but it's a different filesystem so you
need some different commands that make more sense for how it's
structured. The idea being hopefully that soon zpool and zfs
commands will become just as 'intuitive' for people :)

(p.s. not to mention am I the only person that thinks that 'zpool
status' (in human speak, not geek) makes more sense than 'df'? wtf )

For creating a filesystem, I agree it is, as I could do that easily
without a man page.
However, I found it rather surprising that I could not see the
physical device(s) a zfs filesystem was attached to using either
"df" command (that shows physical device mount points for all other
file systems), or even the "zfs" command.
Even going to "zpool" command it took a few minutes to finally
stumble across the only two commands that will give you that
information, as it is not exactly intuitive.
Ideally, I'd think "df" should show physical device connections of
zfs pools, though I can imagine there may be some circumstances
where that is not desirable so perhaps a new argument would be
needed to specify if that detail is shown or not.
If this is not done, I think "zfs list -v" (-v is not currently an
option to the zfs list command) should show the physical devices in
use by the pools.
In any case, I think it is clear "zpool list" should have a "-v"
argument added that will show the device associations, so that
people don't have to stumble blindly until they run into the "zpool
iostat -v" or "zpool status -v" commands to finally accomplish this
rather simple task.
Any comments on the above? I'm using S10 06/06, so perhaps I'll
get lucky and someone has already added one or all the above
improvements. :)
Cheers,
Bruce
