[OpenIndiana-discuss] System Panics after deleting zvol

[matt at focusedmobile.com]

Need some help trying to recover data from my zpool (version 28).

You can read all the gory details here:
http://www.nexentastor.org/boards/2/topics/8502

I am unable to import the pool into OpenIndiana live (or any other 
distro) and am expereincing the same kernel panic whenever I try to 
import my zpool after I deleted an old zvol...  long story short I have 
tried every import switch I could find and even ran zdb -e -bcsvL which 
took almost 4 days(screen shots in thread listed above).

Right now I am only able to import the pool as read only, but since 
this zvol was presented to a remote windows host via iSCSI when I try to 
use sdbadm to recreate a LU and map it to the remote host it errors out 
with:
  (Unable to share "ZFS_Pool/File_Store" zvol: Unable to create lu with 
zvol 'ZFS_Pool/File_Store': stmfadm: data file error)

Right now I want to either:
1) Just get the data off the volume and recreate the pool
2) Roll back the Uberblocks to just before I deleted the zvol..

fmdump -eV   (Shows me the following)

When I view the history -il of the pool ( I can see multiple entries 
where it is trying to destory but never completes)
