Unfortunately I don't :(
I'll make a habit of creating a copy from now on!

You're right. zpool export tank seems to remove the cache file so import has
nothing to consult so doesn't make any difference.

I guess my only chance at this point would be to somehow manually edit
the zpool configuration, via the zpool.cache file or not, and substitute
mfid with gpt/disk?!
Is there a way to do this?
