I have a problem that could either be easily solved, or potentially coul
dhave me royally screwed.
I had a FreeBSD 8.0 system crash on me, and I lost some binaries
including zfs tools. I tried fixing with Fixit but had no such luck so I
rebuilt world and kernel on a fresh hard drive. The old system had zpool
raidz containing da0 and da1. Because of the crash I didn't get to
export this pool, but when I try to import now I get this:
# zpool import tank
cannot import 'tank': one or more devices is currently unavailable
If I take I look at the list I only see this:
# zpool import
pool: tank
id: 4433502968625883981
state: UNAVAIL
status: One or more devices contains corrupted data.
action: The pool cannot be imported due to damaged devices or data.
see: http://www.sun.com/msg/ZFS-8000-5E
config:
tank UNAVAIL insufficient replicas
da1 ONLINE
if I list destroyed pools:
# zpool import -D
pool: tank
id: 12367720188787195607
state: ONLINE (DESTROYED)
action: The pool can be imported using its name or numeric identifier.
config:
tank ONLINE
da0 ONLINE
TADA! There's the missing drive. So what happened?
if I debug each drive...
bad drive:

One thing that stands out to me is that they have different hostnames.
da0 has the box's current hostname "proj", while da1 has the previous
box's hostname "zproj"... could this be the issue? If so, how to I
change it in this state?
But wait, a look at dmesg reveals:
da0: 6674186MB (13668734464 512 byte sectors: 255H 63S/T 850839C)
GEOM: da0: corrupt or invalid GPT detected.
GEOM: da0: GPT rejected -- may not be recoverable.
Could the drive just be completely effed? If so, then I think I am too.
Please help!
