Sorry for reviving this old thread.
I even have this problem on my (productive) backup server. I lost my system-hdd
and my separate ZIL-device while the system crashs and now I'm in trouble. The
old system was running under the least version of osol/dev (snv_134) with zfs
v22. After the server crashs I was very optimistic of solving the problems the
same day. It's a long time ago.
I was setting up a new systen (osol 2009.06 and updating to the lastest version
of osol/dev - snv_134 - with deduplication) and then I tried to import my
backup zpool, but it does not work.
# zpool import
pool: tank1
id: 5048704328421749681
state: UNAVAIL
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.

# zpool import -f tank1
cannot import 'tank1': one or more devices is currently unavailable
Destroy and re-create the pool from
a backup source
Any other option (-F, -X, -V, -D) and any combination of them doesn't helps too.
I can not add / attach / detach / remove a vdev and the ZIL-device either,
because the system tells me: there is no zpool 'tank1'.
In the last ten days I read a lot of threads, guides to solve problems and best
practice documentations with ZFS and so on, but I do not found a solution for
my problem. I created a fake-zpool with separate ZIL-device to combine the new
ZIL-file with my old zpool for importing them, but it doesn't work in course of
the different GUID and checksum (the name I was modifiing by an binary editor).

doesn't gave me the GUID of the old ZIL-device and ends without a prompt (the
prozess hangs up).
