zfs discuss - Jul 2011 - Recover data from detached ZFS mirror

Does anyone know where the "Jeff Bonwick tool to recover a ZFS label"
is?

The old link was: 
http://www.mail-archive.com/zfs-discuss at opensolaris.org/msg15620.html

But it does not exist anymore.  I have a zfs detached disk that was part
of a root mirror and I need to boot from it. 

Thank you for any information.

Hi Judy,

Without much to go on, let''s try the easier task first.

Is it possible that you can re-attach the detached disk back
to original root mirror disk?

Thanks,

Cindy

Hi Cindy,

Well, the other half of the zfs mirror is on a truck via snail mail to
another location.  We thought we were saving a copy of the root disk when
we did a zfs detach.  We didn''t know it would remove the zfs label
information.  Is there a way to get the disk back to a "bootable"
state?

Thanks,

Hi Judy,

The disk label of the detached disk is intact but the pool info is no
longer accessible so no easy way exists to solve this problem.

Its not simply a matter of getting the boot info back on there, its the
pool info.

Your disk will have to meet up with its other half before it can be
bootable again is my assessment.

Many experts are on this list so maybe they will have a suggestion.

Thanks,

Cindy
