Use 'dd' to replicate as much of lofi/2 as you can onto another device, and then
cable that into place?
It looks like you just need to put a functioning, working, but not correct
device, in that slot so that it will import and then you can 'zpool replace' the
new disk into the pool perhaps?

Yes, that's what I meant.

It's interesting that even though 4 of the 5 disks are available, it still
can import it as DEGRADED.
I agree that it's "interesting". Now someone really knowledgable will
need to have a look at this. I can only imagine that somehow the
devices contain data from different points in time, and that it's too
far apart for the aggressive txg rollback that was added in PSARC
2009/479. Btw, did you try that? Try: zpool import -d /dev/lofi -FVX
ZP-8T-RZ1-01.
Hi again,
that got slightly further, but still no dice:

or invalid. There are insufficient replicas for the pool to continue
functioning.
