zfs raidz2 - insufficient replicas
I lost my system volume in a power outage, but fortunately I had a dual boot and I could boot into an older opensolaris version and my raidz2 7 drive pool was still fine. I even scrubbed it, no errors. However, the older os has some smb problems so I wanted to upgrade to opensolaris11. I accidentally did the auto install option and it overwrote one of my data drives. This is really important data, but fortunately I have a raidz2, so how bad can it be?... BAD! Booting back into the earlier solaris version I cannot access my pool, This is what zpool status shows:

zpool status
pool: brick3
state: UNAVAIL
scrub: none requested
config:
Code:
    NAME        STATE     READ WRITE CKSUM
    brick3      UNAVAIL      0     0     0  insufficient replicas
      raidz2    UNAVAIL      0     0     0  corrupted data
        c12d0   ONLINE       0     0     0
        c11d1   ONLINE       0     0     0
        c10d1   ONLINE       0     0     0
        c10d0   ONLINE       0     0     0
        c8t0d0  ONLINE       0     0     0
        c8t1d0  ONLINE       0     0     0
        c11d0   ONLINE       0     0     0

I tried to export and re-import it, and I get the following message:

zpool import brick3
cannot import 'brick3': invalid vdev configuration

please please please help, what do I do.

zdb

zdb(1M) 						  System Administration Commands						   zdb(1M)

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.
