Shrinking zpool
Hello experts,

I have a solaris 10 (SunOS 5.10 Generic_148888-05 sun4u sparc SUNW,SPARC-Enterprise) that by mistake I added a second san space of 700g to the pool. the whole pool is now 1.2T and, I need to take the space away from the pool and, make the pool 700g total. this is live oracle filesystem. I have not done any zfs shrinking of sort (I know you can not do this). Here is my zpool status

Code:
# zpool status DLMS01Cpool
  pool: DLMS01Cpool
 state: ONLINE
status: The pool is formatted using an older on-disk format.  The pool can
        still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'.  Once this is done, the
        pool will no longer be accessible on older software versions.
 scan: resilvered 392G in 2h36m with 0 errors on Thu Apr 19 20:08:46 2012
config:

        NAME                     STATE     READ WRITE CKSUM
        DLMS01Cpool              ONLINE       0     0     0
          c3t50002AC17D9D072Bd0  ONLINE       0     0     0
          c3t50002AC21226072Bd0  ONLINE       0     0     0

errors: No known data errors

what are my best options? Can you give me the commands please?

Zpool mirroring

Now this doesnt look right to me. All of these disks are 100Gb LUNS so total zpool size is 300Gb. Am I right in saying that this zpool consists of two disks plus one more disk that is 6 way mirrored?

zdb(8)							  System Administration Commands						    zdb(8)

NAME

       zdb - ZFS debugger

SYNOPSIS

       zdb pool

DESCRIPTION

       The  zdb command is used by support engineers to diagnose failures and gather statistics. Since the ZFS file system is always consistent on
       disk and is self-repairing, zdb should only be run under the direction by a support engineer.

       If no arguments are specified, zdb, performs basic consistency checks on  the  pool  and  associated  datasets,	and  report  any  problems
       detected.

       Any options supported by this command are internal to Sun and subject to change at any time.

EXIT STATUS

       The following exit values are returned:

       0    The pool is consistent.

       1    An error was detected.

       2    Invalid command line options were specified.
