Hello,
I had a pool made from a single LUN, which I'll call c4t0d0 for the
purposes of this email. We replaced it with another LUN, c4t1d0, to
grow the pool size. Now c4t1d0 is hosed and I'd like to see about
recovering whatever data we can from the original LUN, c4t0d0.
I can still see the ZFS labels on t0 with zdb [1], but it is not
available for importing (even with zpool import -D). Are there any
tools available for me to tweak the metadata on the old LUN so that I
can import it? Is there anything else I can try?
I am using Solaris 10 U9, and before anyone says anything, our SAN guys
don't really understand ZFS or else I would have made the pool redundant
in the first place.
Thanks,
James
