Incorrectly re-synced vinum subdisk

Tonight while checking a few things on my personal machine I noticed
that one of my vinum sub disks was stale. Included below are the
steps I took attempting to remedy this. Clearly I did not follow the
proper procedures and now the volume is un-mountable. Currently when
I attempt to mount the /export filesystem the machine panics and
reboots. My apologies in advance for the length of information
included. I include it so that it might aid in recovery of the data
on this filesystem. It has been cleaned up a bit but am happy to
provide the full output with the multiple "help" command output.
Shortly after the command sequence included the machine rebooted.
Since then I have booted in to single user mode and commented out
/export from fstab. The machine is fully functioning with the
exception of the important data on /export.
If anyone doesn't believe I will be able to recover the data on my own
but does know of a company that might be able to recover data written
on a vinum mirror would you send me their name?
Thank you
Ahnjoan
