I have had a little think about this problem during my break and I now realise that the information that you are looking for will not be easy to come by, the nature of ZFS makes it increasingly difficult as you add more disks to the zpool.
ZFS dynamically creates a block to vdev relationship based on block size (recordsize) and the number of disks in the pool. So if we create a pool with four disks and a block size of 128k (default), the blocks are allocated basically on a round robin basis across the four disks.
So identifying a file system to vdev relationship will not be easy, you could tackle it like this;
Now you have to go and have a look at the output and find what you want - but be warned;
Getting the required output;
Where I have a single line across the bottom (beginning with 0), your pool should show 5 lines - one for each vdev you should be able to see which vdev the output was written to. If you write a file bigger than 640K it will write at least one block to each - zfs manages that bit. As for the zfs file systems they are striped across however many disks are in the pool.
Can you tell us what the hardware is, this looks suspiciously like the view from inside an ldom.
Please post the output from echo | format (or a part of it if it's too big ) and if possible /usr/sbin/virtinfo -a this will give a good starting point.

Hello all,
I'm sharing 1 volume from a Sun Storage array (6130), out to 2 servers. Created a slice on one server and mounted a filesystem. On the other server the disk already sees the created slice from the other server (shared throught the storage array, so mounted this filesystem as well.

Dear Gurus,
Could it be possible to have the output of df -k sorted? The df -k output messed up after recent power trip.
Also, is there any folders that I should look into to reduce the root size (other than /var/adm and /var/crash) after server crash?
Many thanks in advance.
