zfs discuss - Aug 2009 - Honey, I blew up the zpool! Help me get my pool back from my noobness!

Hi.
I recently transferred a zfs drive containing one pool from a FreeNAS 0.7RC1 box
to a FreeNAS 0.7RC2 box.

I had earlier reinstalled the first box several times, and managed to get the
pool back just using the FreeNAS gui. However, after moving the drive to the new
box, and doing the same procedure, it created a new pool, and all the data is
gone. Or, the data isn''t gone, the drive reports 25Gb being used, but
the new pool contains nothing. Is there any way to rescue the old pool? I have
tried "zpool import" and all the stuff I have found by googling, but
they only find the new pool I created.

I don''t necessarily need the pool itself back. But the data would be
nice to have since there are unbackuped family photos and stuff there... (Yes I
know... But I was going to setup the offsite backup _after_ migrating to the new
box :( )

Any suggestions?

Christian
Norway.

Only in the FreeNAS physical disk info. All zpool commands only
display info about the last pool i destroyed/created (which isn''t the
one I''m looking for). But I don''t think i have tried the
history
command... "zpool history" ?
